Senate Majority Leader Harry ReidHarry ReidDems face identity crisis Heller under siege, even before healthcare Charles Koch thanks Harry Reid for helping his book sales MORE (D-Nev.) predicted this week that it will be "easy" to win the 60 votes needed to pass immigration reform in the Senate.

"I think we have 60 votes," Reid said in taped television interview, according to the Las Vegas Sun. "Remember, we start out at 55 Democrats. I think the most I'll lose is two or three.

"Let's say I wind up with 52 Democrats," he continued. "I only need eight Republicans, and I already have four, so that should be pretty easy."

Reid is expected to take up the Senate's immigration bill, S. 744, once the Senate returns to work in June. The Senate Judiciary Committee approved the bill before leaving in a 13-5 vote — three Senate Republicans supported the bill in committee.

Hatch has proposed amendments that would block the Obama administration's attempt to waive the welfare-to-work requirements in current law, require immigrants on a path to citizenship to pay all unpaid taxes and block these immigrants from using ObamaCare subsidies for five years.
