Walker is not at top of my list, buy I am OK with him. We could do worse. Lack of college degree did not hurt him in Wisconsin. But the unions will mount the most aggressive campaign against Walker after what he did to them in Wisconsin.
This article shows that the NY Times wants the GOP race to be between Walker and Bush. Why? Because they are scared to death of Ted Cruz.
Walker is soft on amnesty, he is pals with GOPe (Priebus, Ryan, and Rove), he broke job creation campaign promises, he was nowhere to be found when Ted Cruz was fighting Obamacare and defending the Constitution, and he is likely to be dogged by (admittedly bogus) ethics complaints.
Conservatives would be crazy to support Walker over Cruz.
