I was a Walker supporter and I will support Cruz in the primaries, but I think he is underestimating the fire that Trump has lit under the American electorate. We’re all growing tired of anyone with an R or a D by their name because it all looks and sounds the same coming out of their mouths. Obviously Cruz is not an establishment guy but he is still part of the political class, so even those who might be inclined to vote for him will vote for Trump because of the fact he’s still a professional politician.
Trump is a 3rd party candidate running for the Republican nomination.
He knows a 3rd party candidate is doomed if a Republican candidate is in the race.... thus he runs under the umbrella of the Republican party.
This is just sooooo obvious IMO.
