You are correct so I withdraw my Obama comment. And, if the Powerline snippet below is correct the switch to the GOP in 2009 makes no sense. I can't figure this guy out. But I struggle to get pumped up about someone who was a registered Democrat just a few years ago.
From a Powerine article:
Nor did a belief to the contrary cause Trump to tilt to the Democrats. According to this account, Trump was a registered Democrat from 2001-2008. He switched his registration the very year that, in his telling, the Republicans crashed the economy.
In truth, Trump is a natural Democrat. His views on major issues are or were until recently standard-issue liberal.
Power-line is interesting but Establishment Gop all the way.
