Fred Thompson to announce his candidacy Sept. 6

DES MOINES, Iowa (AP) ‘ Republican Fred Thompson will officially launch his presidential bid Sept. 6 in a Web cast on his campaign site, followed by a five-day tour of early primary states.

‘I believe that there are millions of Americans who know that our security and prosperity are at risk if we don’t address the challenges of our time; the global threat of terrorism; taxes and spending that will bankrupt future generations, and a government that can’t seem to get the most basic responsibilities right for its citizens,’ the former Tennessee senator and ‘Law & Order’ actor said in a statement Thursday that laid out themes of his campaign.

Thompson, 65, is vying to be seen as the most consistent mainstream conservative in the race.

Aides disclosed details about how he will formally enter the race in a conference call with supporters.

Evening house parties will be held nationwide Sept. 6. A tour of Iowa, New Hampshire and South Carolina will quickly follow the Internet announcement on www.imwithfred.com, with later stops in Florida, and a homecoming event in Lawrenceburg, Tenn., on Sept. 15.

Thompson brings to the eight-man GOP field a right-leaning Senate voting record with a few digressions from GOP orthodoxy and a healthy dose of Hollywood star power. He is hoping to attract conservatives who are lukewarm about the current crop of candidates.

Earlier this year, Thompson saw his popularity soar in polls when he acknowledged he was considering a run. Since then, he’s consistently ranked among the top Republicans in national polls and surveys in key states alike. In April, he disclosed that he was diagnosed in 2004 with non-Hodgkin’s lymphoma, a highly treatable form of cancer.
