Looks like Paul really stepped in it this time, lol, he should have learned from McCain, Bush, Perry. I think his plan is better then others put forward in the past. But he has lost a lot conservative support. If something gets pasted in Congress and I think that is likely Paul will take the fall for it.
Senators make for poor Presidential candidates for this very reason.
No executive experience, and they have a trail of the things they voted on, which over a course of time will tend to be contradictory.
