The Senate is bumping a vote on legislation to codify the right to marriage equality until after the midterm elections, senators announced on Thursday.

Why it matters: The development highlights the challenge senators whipping support for the bill have had wrangling 10 Republican votes on such a sensitive social issue in the run-up to the Nov. 8 election.

The backdrop: Only a handful of Senate Republicans have said publicly they plan to vote for the legislation.

• Senators working on the bill have been crafting a religious freedom amendment to get more Republicans on board, but this week they began to raise concerns that they would run out of time.
• Senate Majority Leader Chuck Schumer was expected to tee up a vote for early next week.

What they're saying: “We’ve asked Leader Schumer for additional time and we appreciate he has agreed,” said Sens. Tammy Baldwin (D-Wis.), Susan Collins (R-Maine), Rob Portman (R-Ohio), Kyrsten Sinema (D-Ariz.), and Thom Tillis (R-N.C.) in a statement.

• “We are confident that when our legislation comes to the Senate floor for a vote, we will have the bipartisan support to pass the bill,” they added.

What we're watching: Schumer's spokesperson Justin Goodman said in a statement the Democratic leader is "100 percent committed" to holding the vote before the end of the year.

• "[He] will hold the bipartisan group to their promise that the votes to pass this marriage equality legislation will be there after the election," Goodman said.
