Meanwhile, in New Mexico, former Nevada tea party favorite Sharron Angle endorsed Greg Sowards. Sowards is a long-shot candidate running to the right of both former Rep. Heather Wilson and Lt. Gov. John Sanchez.
"The battle for the soul of the GOP is ongoing in New Mexico. Greg Sowards is our only opportunity to advance conservatism," Angle wrote in an email to supporters after bashing Sanchez and Wilson.
As with Stenberg, the true test of the endorsement will come in a few weeks as third quarter reports come in. Like the Nebraska treasurer, Sowards's fundraising has not been impressive and most of the money in his camapign account has come from his own pockets.
If Sowards's profile is raised as the race goes on, the likely beneficiary is Wilson; Sowards is more likely to eat into Sanchez's support as Wilson is to the left of both Sowards and the lieutenant governor.
Not to be outdone, Sanchez was endorsed by Sen. Rand Paul, R-Ky., Tuesday.
"The voters of New Mexico want more of Barack Obama, Harry Reid and Nancy Pelosi they have plenty of choices, but if they want a true conservative to look out for the taxpayer, I hope they'll join me in supporting John Sanchez," Paul said in a statement.
