It's ironic...the GOP created and catered to these far-right extremists for short-term gain in 2010, now the same extremists are killing their chances of winning in 2016 or even 2014. Let's not even mention the Senate seats they lost because of crazy Tea Partiers.
Because of them, their base will never be happy unless they go so ridiculously far right that they'll never win a national election. They created a monster, and now that same monster is eating them.
