As of 6/5/13, Rubio will not vote for Senate bill as passed out of committee

The legislative process, especially on a bill this many moving parts, is a long and winding road.  This week, Marco Rubio (R-FL) seemed to be walking away from the very immigration bill he has been the public face of.  After the Gang of 8 spent many grueling markup hours defending the bill from poison pill amendments, before successfully reporting the bill out of committee with a 13-5 vote, Rubio this wee said he needs more enforcement measures in the bill before he can vote for it.  He made clear he would not vote for the bill as passed out of committee. According to Byron York of the Washington Examiner, Rubio said the following on Hugh Hewitt's radio show:

Hewitt:   “If those [additional enforcement] amendments don’t pass, will you yourself support the bill that emerged from Judiciary, Senator Rubio?”

Rubio:   “Well, I think if those amendments don’t pass, then I think we’ve got a bill that isn’t going to become law, and I think we’re wasting our time. So the answer is no.”

If Rubio bails on his own bill, that would give more reason for already reluctant House GOP members to follow suit.  It is not clear at this point whether Rubio is playing hardball to get more enforcement measures in (what these would be are not clear) or whether he really is willing to walk away from a bill he sank so much of his political resources into because he doesn't think it will pass.
