We will see in 2014. My guess, the libs are in trouble.
This reminds me of way back in 1976, when Reagan challenged Ford. Though he lost that one, something remarkable happened. His campaign brought out hundreds of thousands of voters who had never participated before. They were thrilled with Reagan and were there for him in 1980.
Same thing with Ted Cruz. Lots of people are just sitting up now and taking notice. They are inspired by him and will be there in 2014 when the conservative candidates run.
