Walker never had any real funding. I suspect that he added up the numbers and knew by October that he’d be heavily in debt and just said he didn’t want to dig out. My guess is that whoever wins in November of 2016....might hire him for a cabinet post. If not...Baldwin’s senate seat comes up in 2018 and he could easily beat her.
I would say this....back six months ago...I thought Walker would last out and be number two behind Bush at the Convention (figuring the establishment an control folks would ensure Jeb’s position). I’d go ahead ahead and predict that Jeb will barely have the funding to survive until the Iowa primary.
Walker would have done himself a favor if he had called in sick to the debates. He looks like a teenager. People just can't picture that face in a facedown with someone like Putin. Rubio has the same problem. Baby faces. No perceived Gravitas.
Cruz and Trump both have what Walker and Rubio lack. Trump has it in spades.
Fiorina, Walker, Rubio all look weak on stage. I'd put Linda Graham in that category, but she is polling worse than Walker and Walker just dropped out.
