This is the cloture vote that will separate the supporters of the immigration reform bill from those who want to see it fail. So if any Republican votes to end cloture on this bill, allowing it to move to a final vote, they undoubtedly want to see it pass and therefore will be seen as supporting the bill, no matter how they vote on the bill for final passage:
THE HILL – Senate Majority Leader Harry Reid (D-Nev.) said Tuesday that he would file cloture on the immigration reform bill by the beginning of next week.
“We’re going to either file cloture on this Friday, Saturday, Sunday or Monday … so I urge people to come out with amendments,” Reid warned senators. “The time has come to make decisions on this important legislation.”
The Senate began its formal debate on immigration reform last week and is scheduled to vote on four amendments to the bill on Tuesday. Reid’s cloture motion would end debate on the bill if it wins 60 votes.
Reid has said he hopes to finish work on the bill before the July 4 recess, and warned again Monday that senators might be required to work this weekend.
“I would hope that people understand that this may not be one of our normal weekend where we shoot out of town,” Reid said.
