True, and not inviting Palin to speak at the GOP convention and practically barring any mention of Tea Party sentiment cost them many votes in 2012. Such stunts as that and amnesty would cost them more votes in the future.
They'd be be better off forgetting about the Obama/Schumer/McCain/Rubio amnesty, but they won't.
I remember too that the foolish Bob Dole wouldn’t let Pat Buchanan speak in San Diego in 1996; couldn’t have helped Dole in the least. Then E. Dole took the Helms seat and squandered it away.
