The powerful Bush clan is playing an increasingly prominent role in Georgia's Senate race.

After George H.W. Bush

, his son, Neil Bush, denounced the

Democrat Michelle Nunn's nonprofit to "terrorists." Neil Bush has a vested interest in the debate: He's the chair of the nonprofit, Points of Light.

This morning, we received this statement from Jim McGrath, the elder Bush's spokesman:

In terms of TV ads, it was the regrettable use of his photo by the Nunn campaign earlier this year – not only without his prior permission, but even after his objections were privately communicated to the Nunn camp – that, he felt, forced his hand to get involved. President Bush felt very strongly that he had to clear up any erroneous perception as to who he supported in this critical race for America's future.

Now that he has enthusiastically endorsed David Perdue and addressed the unfortunate development that prompted him to get involved in the first place, he firmly believes it is up the candidates make their own case to the voters of Georgia. The voters should, and always do, have the final say."

There's still time for Jeb and George W to get involved, too.

The latest Rasmussen Reports survey has Republican David Perdue slightly ahead of Democrat Michelle Nunn.

The telephone survey puts Perdue at 46 percent and Nunn at 41 percent. About 4 percent of the respondents prefer another candidate, and nine percent haven't made up their minds yet.

Secretary of State Brian Kemp's office is pushing back against the notion that "only minor problems" have been found in an investigation into voter registration fraud by a Democratic-backed group.

Kemp's office released a "fact check" that warned forged signatures can lead to disenfranchisement and said the Democratic group, New Voter Project, was not targeted.

There was also this nugget:

This investigation has only just begun. The State Election Board meeting yesterday was held to reaffirm a subpoena issued to continue investigating this possibly criminal situation. The presence of confirmed forgeries is not the conclusion, but rather only the beginning of this investigation.

The Democratic Senatorial Campaign Committee sent over the above hijacked version of David Perdue's latest ad, which criticizes Michelle Nunn for supporting "amnesty" - his view of the immigration overhaul bill that passed the Senate.

You'll see that Sens. John McCain and Marco Rubio, two supporters of that effort, were inserted in the beginning of the clip.

David Perdue hosted a roundtable discussion with military veterans yesterday, and used the occasion to blast President Barack Obama's foreign policy.

Morris News Service's Walter Jones was there, and he noted that Perdue deflected questions about whether he would support specific military options. From his piece:

The Republican's main point on national defense Thursday, and throughout the campaign, is that the biggest danger he's focused on is the federal debt because it undermines the ability to fund manpower and equipment.

"I am fully supportive of maintaining a strong capability in our military," he said. "We have to do that if we are going to have any type of foreign policy that's consistent to protect our national interest and our national security. But to have a strong military, again I go back to the issue: you have to have a strong economy."
