Some Thompson supporters are getting restless.
WASHINGTON (CNN) - For the online supporters urging "Law & Order" actor Fred Thompson to run for president, it's turning into a long summer.
Since May, the former Tennessee senator has been "testing the waters" for a 2008 White House run, launching a campaign Web site and beginning to raise money. A senior adviser confirmed to CNN that the actor and former senator will officially launch his bid for the White House after Labor Day.
But that may not be soon enough for many of his supporters. The self-described "Fredheads" – who populate scores of unofficial Fred Thompson blogs, forums and draft Web sites – are ready to jump in and join him now.
"What's the hold up?" wrote Keith Harper, who operates a forum called FredHeads.com out of Chattanooga, Tennessee. Harper said he didn't want to second-guess a politician's sense of timing, but said he worries Thompson's grassroots support could dwindle if he waits too long.
Since spring, Thompson has been cultivating a loyal following among conservatives online, regularly posting on blogs and right-leaning Web sites. Blogs supporting Thompson abound, and a crop of unofficial draft sites have gathered tens of thousands of signatures of people ready to support a Thompson bid.
Jeff Mitchell in Memphis, Tennessee, who has run the site DraftFredThompson.com since January, notes an "increasing anxiety" among the Fred faithful.
"New people come in, and 4-6 weeks after they come, they're still waiting," Mitchell said. But he thinks supporters are "anxious and excited" to get involved, rather than discouraged by the wait.
Robert Traynham, a spokesperson for Thompson, said the senator is "flattered" by all the support and "will hopefully have an answer for them, one way or another, sometime in the very near future."
Despite the assurances, "everyone is starting to get impatient," said Erick Erickson, managing editor of the popular conservative blog RedState, where Thompson enjoys significant support and where his own posts frequently appear.
"We all understand the reasoning," Erickson told CNN, "but as my wife said, ‘I'm tired of flirting. It's time to put up or shut up.’
"That said, it's much like the excitement over the iPhone,” he added. “By the time it was released, people were standing in lines across the country waiting."
