Just one week remains until Texas holds its midterm primaries, which will be highlighted by the race for the Republican nomination for governor. Incumbent Rick Perry has been successful holding off a competitive challenge from Sen. Kay Bailey Hutchison, leading now by 15 points in the RCP Average, which includes a 16-point lead in the latest Dallas Morning News poll.

With just days left to go, both campaigns are hitting the airwaves with attack ads. Perry goes after Hutchison in an ad called, "The Queen (of earmarks)," which accuses the senator of supporting wasteful earmarks for other states and ties her to unpopular Washington.

Hutchison is up with an ad titled, "Fueled," which highlights negative newspaper clips on Perry -- including stand-alone quotes like "ethical clouds" and "cronyism."
