Some people (I'm looking at you, skeptical Kossacks), seem to think that Donald Trump's recent expression of some particularly EEG flat-line right wing ideas might indicate a certain lack of sincerity on the part of the fast-talking businessman/celebrity/politician/comb-over hair maven.
Oh ye of little faith! Donald Trump just wants to make sure he qualifies for the Republican presidential nomination in all states, including Arizona. Of course, Arizona's strict candidate rules (like male circumcision--sorry, ladies) apply only to Democratic candidates. For Republicans, a candidate may qualify by simply displaying their Republican Lobotomy Certificate (RLC), which can be obtained at any time by swearing to believe one or more of the following totally ridiculous statements:
1) Obama is a Kenyan Muslim
2) There is no scientific proof that humans cause climate change
3) Abortion is murder, but murdering family planning doctors is justifiable homicide
4) Tax cuts increase revenue
5) Zero corporate regulation fixes all problems with the economy and the environment
6) The best way to reduce gun violence is for everybody to carry a gun
7) States can pick and choose which federal laws they enforce or ignore
8) There is no acceptable evidence of biological evolution, but..
9) An invisible, untraceable, intangible "god" is behind everything, and...
10) He only likes white people, who should own everything and always be the boss.
Note: An actual lobotomy scar is optional, but an endorsement by Sean Hannity is considered the equivalent of any of the above statements.
Trump is merely making sure he qualifies as a Republican candidate. He's also making sure he's in the center ring of the media circus, so his TV show ratings go up.
