Must I hit my hands daily with a hammer as to learn to tolerate pain also? LOL. In the end both voting for GOP-E and bashing your fingers with a hammer only results in a bloody painful mess. I'll support Good Republicans to the hilt.
I don't expect perfection thus ones like Duncan in my eyes are acceptable. Many don't even likely know who he is but he's a reliable Conservative just about every time even against the party. But I won't vote for ones like Lamar Alexander or Corker for even county dog catcher. They both are in office thanks to DEMs skewing the primaries. Simple solution is have closed primaries and a one primary election cycle lock out placed ones changing parties.
As for POTUS primaries? The only hope I see there primary wise is to have a true National Democrat and GOP Primary held on the same day. One primary national vote say in July. This way we all get an honest say in the matter.
That would only work if both had contested primaries, otherwise the Dems would engage in chicanery with our side as per usual. But we need to REGISTER voters by party and enact runoffs for less than 50%. No more plurality victories by people reflecting only a minority of the base voter preference.
