Think of today as a microcosm of the Texas Senate race.
Republican Lt. Gov. David Dewhurst, whose frontrunner status can be credited to his high name ID, wealth and strong fundraising , flexed each of those muscles today by releasing his first television ad of the race, a six figure cable buy that includes no mention of his opponents.
Former state Solicitor General Ted Cruz, meanwhile, announced the endorsement of Dr. James Dobson, an influential evangelical conservative figure. He's the latest in a parade of national figures -- including Sens. Jim DeMint, R-S.C., and Mike Lee, R-Utah -- that have caught the eye of this outlet, among others, but hasn't so far moved the needle much in his favor, as Kevin Brennan argued last week.
