In the U.S. Senate race so far, GOP Senate candidate Joe Miller has been relatively quiet and has not appeared to be actively fundraising. That looks like it’s changing. A fundraising email that he sent out today indicates that his campaign is gearing up.

“I can also assure you my opponents will never stand up and be counted in these tough battles. Commissioner Dan Sullivan is Karl Rove’s man in the race, a dubious distinction Sullivan publicly embraced over the weekend,” he wrote.

It’s unclear what Sullivan did over the weekend that would indicate that he embraced Karl Rove, who has not endorsed yet in the race. It is clear, however, that Sullivan is the target of Miller, the other GOP candidate Mead Treadwell, and Sen. Mark Begich.

Miller goes on to list Sullivan’s donors, including former head of the World Bank, the former chairman of the Board of the New York Federal Reserve, and the former chief of staff to President George W. Bush, among other lobbyists and financial executives.

In more Miller news: He was endorsed by the National Association for Gun Rights PAC on Tuesday. The NAGR is a gun rights group like the NRA, but much more rigid, more political, and less compromising than that NRA. The PAC is also a relatively small one compared to the NRA, which hasn’t yet endorsed in the race.

As of Dec. 31, the NAGR PAC had $172,161 on hand and had contributed $37,000 so far in 2014. In comparison, the NRA’s PAC had more than $12 million cash on hand at the end of January, and has contributed $246,750 to candidates so far this year.

NAGR is, however, powerful and is credited for helping to pass gun laws in state Legislatures across the country.
