The GOP contenders vying for the open seat of retiring Sen. Pete Domenici (R) have continued their scathing attacks as the June 3 primary vote nears.

Last week, Rep. Heather Wilson (R) launched a new ad (subscription) chastising Rep. Steve Pearce (R) for voting in Congress to cut Social Security for widows and orphans, and to cut state hospital funding. "Steve Pearce: Cut Social Security. Cut New Mexico hospitals. Wrong for New Mexico," the announcer seethes. "With that record, he can't win in November."

The ad's hostile tone is similar to attack ads both candidates released in early May, which set the stage for the GOP battle. The Club for Growth has also run a series of ads in the state charging Wilson with being too liberal.

With the general election season just a week away, the Democratic candidate, Rep. Tom Udall, will likely benefit the most from these ad wars. He doesn't face any opposition in his party's primary, and he has more money than both Republicans.
