From The Hill:
"The bill will pass. I think we're on the verge of getting 70 votes. That is my goal," [Senator Lindsey] Graham said on "Fox News Sunday." "We're very, very close to 70 votes. The Hoeven-Corker amendment I think gets us over the top."The Senate is slated to vote on the border security amendment by Sens. Bob Corker (R-Tenn.) and John Hoeven (R-N.D.) on Monday. The amendment is viewed as key to securing more GOP votes for the bill.Senate Majority Leader Harry Reid (D-Nev.) wants to finish work on the sweeping immigration bill this week and hold a vote to end debate on the underlying bill on Thursday.
Graham, a member of the bipartisan Gang of Eight, called the Corker-Hoeven amendment "the most aggressive attempt to control the Southern border and regain our sovereignty."
Given how notoriously dysfunctional the Senate is, it would be something of a miracle to get 70 votes for anything. The good news is that when the non-partisan Congressional Budget Office scored the immigration bill, they stated that it would reduce the deficit by $197 billion over the next decade.
