Sure is. You see, the GOP blames everyone else for their losses without looking within. Never mind the base adopts unpopular stances on issues. Never mind that the general public does not want more war. Nevermind that the GOP immigration policy is somewhat inhumane. Never mind that the majority of America is pro-choice.
This philosophy that the primary Cruz advisor has accepted will absolutely blow up in their face if he is the nominee. Republicans seem to want to believe Latinos and Blacks will not vote in mass this time. That sounds to me like a fatal belief.
The Dems don't necessarily take the right stance every time, but unlike the GOP, they don't take the WRONG stance EVERY time.
