That's funny. Yes, Michael Moore gets "air time" for pointing out economic, gun control, etc. issues. Just because someone doesn't agree with you politically and has views drastically different than yours, doesn't mean they are nuts. I don't think Michael Moore is in Sarah's league. Air Time??? None of the people you pointed out were seriously considered for the highest and second highest office in the US (and if you are on the ticket for VP, you are being considered as president). Please, don't even try to compare the level of exposure or the possibility to put someone in a political office that means something.
I'm a lousy democrat, but the republican party HAS put Palin on the ballot as one of their standard bearers and MAY do the same with Trump. Those people are in a different league when it comes to being charlatans.
My mother is a staunch republican who I consider to be a "true" conservative and I respect that. She believes in civil liberties, supports gay rights, believes in the right to bear arms (with background checks), women's rights, etc. In my opinion, the "conservative" movement has been hijacked by a bunch of religious bigots (Pat Robertson and his ilk).
Barry Goldwater Sr. supported gay rights long before it was fashionable. While I would disagree with him on a plethora of issues, Sarah Palin and Donald Trump don't deserve to wash his dirty socks and have less integrity in their entire body than he had in his fingernail.
