How Did Marco Rubio Get Attached to This Immigration Bill?
Three theories about Marco Rubio:
1) He has made a cold-eyed calculation that the approval of big Republican donors and Rupert Murdoch will matter more than the disapproval of talk radio and the conservative activist base;
2) He got played;
3) He was never really that excited about immigration enforcement in the first place: that message was for 2010, and this is now.
