Joe Carr has to do a better job of getting his name out over the TV and radio airwaves. Alexander is hammering the airwaves.
Tea party people want candidates to step up and run against the GOPe but those candidates get no $$$$upport. They've only succeeded in rare cases where the GOPe opponent has been so repulsive or incompetent that they damaged themselves with their own campaigns (cf. Dewhurst).
Donate to Carr's campaign. It takes money to "hammer" the airwaves.
