Cornyn starting to sweat a bit?

Texas Sen. John Cornyn, with a 10-1 cash advantage over challenger Rick Noriega, has a lead of less than 10 percentage points in external polls. But, he and campaign manager Rob Jesmer are still worried. An internal memo by Jesmer says:

“We are operating in an extremely volatile and fluid political climate. … we will likely have to navigate some bumpy days as the election approaches.”

Jesmer expects Noriega to start running TV ads Thursday. And, don’t forget Thursday’s debate at 8 p.m. on KERA and other public TV stations. Unfortunately, no third-party candidates are included.
