The seven Democratic senators whose votes could be key to ending the government shutdown

• Sens. John Fetterman (D-Penn.), Catherine Cortez Masto (D-Nev.) and Angus King (I-Maine), who caucuses with Democrats, were the only ones to vote with Republicans on Tuesday in favor of the GOP's stopgap spending proposal.
• But the longer the shutdown drags on, the more pressure builds on each side to find a solution.

Sen. Maggie Hassan (D-N.H.)

• A moderate, Hassan was one of ten Senate Democrats who voted to break a filibuster of a government funding package in March, clearing the way for Republicans to pass the bill.

Sen. Jeanne Shaheen (D-N.H.)

• Shaheen is one of the Democrats leading the push for a bipartisan compromise on extending Affordable Care Act tax credits. A breakthrough in those talks could unlock her support.
• Like Hassan, she voted in March to help extend government funding. Shaheen is also retiring next year, so the backlash from the Democratic base for a "yes" vote wouldn't matter much politically to her.

Sen. Gary Peters (D-Mich.)

• Peters has signaled that he would be open to supporting a government funding bill with assurances on concessions on health care from Republicans. He, like Shaheen, is retiring next year.
• Peters voted in March to break a Democratic filibuster of a GOP funding bill.

Sen. Dick Durbin (D-Ill.)

• Durbin was one of the Democrats who voted to break a filibuster of the funding bill in March. He is also retiring.

• As Senate Minority Leader Chuck Schumer's top deputy, however, he'd face additional pressure not to break with leadership's position.

Sen. Jon Ossoff (D-Ga.)

• Ossoff is up for reelection, the most important incumbent race for Senate Democrats next year.
• Depending on where public sentiment goes on the shutdown, he could feel pressure to break with his party to fund the government.

Sens. Kirsten Gillibrand (D-N.Y.) and Brian Schatz (D-Hawaii)

• Both Gillibrand and Schatz voted to break the filibuster in March, raising the possibility of them again crossing the aisle.
• But Schatz has been clear that he is a hard 'no' on the GOP bill this time around, and Gillibrand called looming health care premium increases a "Republican-manufactured" crisis.
• The Trump administration's move Wednesday to withhold $18 billion for New York City infrastructure projects makes it even less likely that Gillibrand would break ranks.
