I challenge the premise that it's CONSERVATIVES who have failed. It's ESTABLISHMENT REPUBLICANS and they are NOT conservatives. They talk differently than the liberal-leftists but they DO the same stuff.
Had the Republicans in Congress been doing what they should have been doing since 2012 when an already fed-up majority put them into the majority of both Houses of Congress then Trump would be a non-issue. Instead they have just rolled on every scheme that Obama has wanted.
The RNC has nobody to blame for Donald Trump than themselves!
On the bright side I see that establishment Republican and RINO Jeb Bush has dropped out. He was the GOP "darling" just a year ago and he spent more money than all the others by a bunch.
BULLSEYE.
