I am not sure Paul would win. I agree that a 40 state victory for Cruz or Walker is possible.
Why do you think Rubio only has a chance.
I agree whole heartily with your observation about Bush-nominate Jeb and we have 4-8 years of Hillary.
Lincoln/Douglas debates is what we need, there are already scheduled debates but when you 10,12 or more candidates in a debate it is all a waste, most debates are 90 minutes to 2 hours, by the time each candidate makes a two or three minute opening remarks, it is nearly half over, then the debate moderators will fix it so the rest of the debate is only between two or three candidates who are the weakest.
We are headed for 2012 again with so many wannabees most who have no business in the competition wasting time, money and resources, and the last man standing is Romney this time Bush and it is all over, Hillary or some other communist takes the prize.
Jeb, Rubio, and Paul have all made permanent fools of themselves.
No serious observer could ever pull the lever for them.
