I think my list right now is Trump, Cruz, Walker.
Cruz is stuck on 5% and has beltway stink on him. Walker is too vanilla and will get destroyed by the MSM/Dem tag team.
That pretty much leaves us with no other option but the Trump, IMO. He’s the only candidate with the fire power to hit the Dems with a flank attack and win.
Another conventional POTUS election = GOP loss in 2016. Guaranteed. The Dems have the formula and cover from MSM to beat the GOP. Trump disrupts all that.
Walker’s had the Democrat/MSM tag team after him twice, and they lost twice. I don’t think that they’d have as much effect as you believe, but with Walker’s choices for his presidential campaign, forgoing his very experienced team to bring in ‘experts’, that’s far more damaging than what the MSM could do to him. Until he gets the brains to go with what he knows works, he’ll be an edge candidate.
