So much money gets thrown at anybody who passes the "litmus tests" that the the Republican party has a field of 17 losers who all looked alike and they were bowled over effortlessly by someone who could pick and choose from the litmus test issues to make a message that actually sells.
If there was not so much money for conservative candidates there might have been fewer candidates and it would have been easier for somebody serious to get some traction. Look at how $100 million got spent on those stupid "Ted Cruz is a flip flopper, you always know where Jeb stands, he stands in the same place as Rhett Butler, Han Solo, and Hillary Clinton..." ads -- in the Citizens United age, spending huge amounts of $$ just makes you look like a jackass.
