So Texas could end up with 2 total lunatics as Senators? I think even with Stockman as the nominee, it would be safe Republican. He'd be running against a nobody Democrat in Texas, after all.
I doubt it. Stockman has a lot of ground to make up with Cornyn's 44 point lead over him, and it certainly doesn't help with the NRA and Right to Life already endorsing Cornyn. However, I was watching msnbc the other day (Yes, criticize me) and Kornacki was mentioning how it was completely expected for Dewhurst to win where out of the blue this extreme conservative whacko pops out of nowhere and gets the nomination (Ted Cruz). So Stockman's chances are low, but in today's politics, an upset is plausible.
But yeah, if Stockman and Scherr end up being the nominees, it will still be a Republican hold. The Democrats in the race suffer from a huge lack of name recognition leaving Texans to go for Mr. "Guns Can Save Fetuses."
