ArizonaMark KellyNot ruling it out"When he's elected, Mark will consider how any changes to the way the Senate does business could help improve the lives of Arizonans."28-Jun-20Huffpost
ArizonaKyrsten SinemaAgainstSinema not only opposes getting rid of the 60-vote filibuster threshold for legislation, she wants to restore the supermajority requirement for presidential nominees that has been weakened by both parties. "They will not get my vote on [nuking the filibuster]," Sinema said .... "In fact, whether I'm in the majority or the minority I would always vote to reinstate the protections for the minority. … It is the right thing for the country."29-Oct-19PoliticoTALLY
CaliforniaDianne FeinsteinNot ruling it out“Ideally the Senate can reach bipartisan agreement....But if that proves impossible and Republicans continue to abuse the filibuster by requiring cloture votes, I’m open to changing the way the Senate filibuster rules are used.”19-Mar-21New York TimesFor28
CaliforniaAlex PadillaForShifting from policy to procedure, Michaelson asked Padilla his stance on the Senate filibuster, a practice which many Democrats, including former President Barack Obama have called to be done away with. Padilla agreed that the practice, which allows a member to extend debate until 60 Senators vote to invoke cloture, should be discarded.23-Dec-20Fox 11 Los AngelesAgainst3

ColoradoJohn HickenlooperNot ruling it out"I would listen to any rule change. I certainly think the way the filibuster is being used now is a joke."28-Jun-20HuffpostUnclear1
ConnecticutRichard BlumenthalFor"I continually to advocate, not just reform, but abolishing it because I think it obstructs the majority," said Blumenthal. "At this moment, we need to get stuff done to meet the unparalleled pandemic and economic crisis that we face in this country."26-Jan-21CT Post
ConnecticutChris MurphyForSen. Chris Murphy of Connecticut said he favors reforming Senate procedure. But he wouldn't elaborate on how that happens. I don't think that it's consistent with the preservation of American democracy as it's used today, Murphy said. "There are lots of different possibilities to reform the filibuster...I think we need to focus on the elections first and then see where we are."5-Aug-20Business Insider
DelawareTom CarperAgainstSome Democratic senators still believe they can gather enough Republican support to keep the filibuster and legislate effectively, especially on job-creating measures like infrastructure funding. "These are bipartisan issues," said Senator Tom Carper.20-Aug-20New York Times
DelawareChris CoonsNot ruling it out"I have long spoken in defense of the filibuster," Coons said. "What I've said was it — and this is very hypothetical — if Joe Biden is the president, if there is a Democratic majority, I won't stand by for four years, and allow every effort to make progress to be blocked."5-Aug-20Business Insider

HawaiiBrian SchatzFor"It's time to trash the Jim Crow filibuster."25-Feb-21Schatz statement
HawaiiMazie HironoFor"I would support getting rid of the filibuster to pass H.R.1. I do think we should look at filibuster reform first and go to the talking filibuster, which is what most Americans think about when they think of a filibuster."29-Mar-21MSNBC
IllinoisDick DurbinFor"I can tell you that's where I'm leaning. I will tell you, I have been frustrated for a hell of a long time because of this filibuster."21-Aug-20Yahoo News
IllinoisTammy DuckworthNot ruling it out"I don't know how we return to where things were before both Harry Reid and Mitch McConnell decided to do the various versions of the nuclear option. I do think that it is pretty harmful when certain laws pass with a simple majority, because then folks in the minority don't have their voice. And our system is set up so that those in a minority should have a voice. But the question then is, should those folks have the ultimate blockage to keep the majority from moving forward? So I don't know where we are on that yet."16-Jul-20New York Times
MaineAngus KingNot ruling it out"As we enter this new Congress with a new president and a new Senate majority (barely), the question for me is how Mitch McConnell and his Republican colleagues will play their hand; if they are willing to work to find compromise and consensus on important initiatives (infrastructure, voting rights or immigration reform, for example), the importance of getting rid of the filibuster diminishes. If, on the other hand, they just say no, the necessity — and likelihood — of filibuster reform would only increase. That is to say, in large measure the outcome is in their hands."24-Mar-21Washington Post
MarylandBen CardinFor“I would be prepared to eliminate the filibuster, but I don’t think you have the votes in the Senate to do it,” Cardin said in an interview. “I’m trying to find a bipartisan buy-in to reforming the Senate. I think that’s far healthier.”15-Mar-21Washington Post
MarylandChris Van HollenFor"Americans should not be robbed of a living wage by archaic Senate rules and procedures—including the filibuster."26-Feb-21Van Hollen statement
MassachusettsElizabeth WarrenFor"That means when Democrats have the White House again, if Mitch McConnell tries to do what he did to President Obama, and puts small-minded partisanship ahead of solving the massive problems facing this country, then we should get rid of the filibuster."5-Apr-19CNN
MassachusettsEd MarkeyFor"The filibuster must go," Sen. Ed Markey told WBUR recently. "It's something that's rooted in a racist past, and it's used today as a way of blocking the progressive agenda, which President Biden is proposing — [including] environmental justice, racial justice, economic justice."3-Feb-21WBUR

MontanaJon TesterNot ruling it outNR: So you could potentially be open now to getting rid of the legislative filibuster?

Sen. Tester: "Well, look. I mean, I've always been open to everything. I didn't come here to not do anything. I came here to get things accomplished. And if people are willing to work together, I'm willing to work with them, and we'll get some stuff accomplished..I think the filibuster serves an important purpose, but I also think that if there's a lot of stonewalling that goes on, it doesn't leave me a lot of choice."

NevadaJacky RosenNot ruling it out“I do not think we should fully eliminate the filibuster,” Rosen said in a statement provided by her office. “It’s one of the few things that we have left in the Senate that allows all voices to be heard. But I am open to looking at and discussing reform proposals, like the talking filibuster, so we can get back to talking to each other and effectively governing on behalf of the American people.”27-Mar-21Nevada Independent

OregonJeff MerkleyFor"And if that means changing or abolishing the current Senate requirement for a supermajority to close debate and pass policy legislation—often referred to as a "filibuster"—then that is what we must do."29-Mar-21Portland Tribune
PennsylvaniaBob CaseyFor"Our democracy is at stake here. I'm ready to work with my Republican colleagues, but should the 60-vote rule (filibuster) continue to be abused against widely popular policies, then we must eliminate – or at the very least reform – the filibuster."9-Apr-21Casey statement
Rhode IslandJack ReedNot ruling it out"I'm focused on the Senate passing legislation that addresses the pandemic, the economy, our defense and our environment," said Senator Jack Reed, Democrat of Rhode Island.

VermontBernie SandersFor"We must pass a comprehensive agenda to guarantee the rights and dignity of everyone in this country. And that means, among other things, reauthorizing and expanding the Voting Rights Act, for which Congressman John Lewis put his life on the line. As President Obama said, if that requires us to eliminate the filibuster, then that is what we must do."30-Jul-20Sanders statement

WashingtonPatty MurrayNot ruling it out"We will see. If they don't, and they just continue to be a smaller and smaller constituency party that just says no to everything and who is willing to live under one loud man's tweets, then it's detrimental and we'll have to have to figure out how I move forward, how we as a country move forward, how I can best represent the interests and fight for what's important in Washington state."18-Feb-21KUOW
