Wendy Davis made a tactical error by running for Governor. She had a better chance of defeating Cornyn, as Tea Partiers will be sitting on their hands (unless he has a primary opponent).
Many years ago my husband and I stopped sending money to political organizations. You never know where the money will end up, even if a conservative heads it up for window dressing. Money needs to go to individual candidates that you know believes as you do.
When we would get calls from the various committees we would just say, heck no, not for that bunch of liberals!
That sends a very clear message.
I agree with your assessment about Wendy Davis.
Her running for Governor is actually GOOD for Republicans! She has no chance to win the Governorship in Texas, BUT, she is going to pull money away from sources that would otherwise go to other states and other candidates. I love it!
