From what I'm reading, much of the GOPe is beginning to understand that, quietly making Rubio their pick.
Both Walker and Cruz will have a tough time beating Rubio if Jeb pulls out early.
He's a bad candidate, I think we should keep encouraging him to run, so the mushy middle vote will be broken up.
Tactics. Think long. Like chess.
I have no real disagreement with that analysis - though I still think it will come down to Walker and Cruz.
I think over time their messages and actions will win out, even over Rubio, who apparently will be formidable - at least early.
Eventually though I think the talk radio and internet universe will reject Rubio, preferring Cruz first and Walker second. I think Walker will have a tiny bit more appeal outside of that universe - which is why I foresee a two person dogfight in the end.
The winner will be the one who ignores the other and focuses on the real enemy.
