The Republicans blew it. They lost the presidential race the day they picked Paul Ryan as the nominee for vice president.
The way you beat the ethnic vote is to join them. They knew they needed help getting the women's vote; they knew they needed help getting the Catholic vote; and they knew they needed help getting the Hispanic vote. So they picked Ryan, who actually polarized the women's vote. They passed up female Gov. Susana Martinez of New Mexico, who would have given them all three things they needed, and they even passed up Sen. Rubio of Florida, who would have given them two of the three things they needed.
Besides, Ryan is so far right of Mitt Romney that he didn't bring one vote that Romney didn't already have.
Surely, Karl Rove knew this. How did he let this happen?
