Blogger launches FEC complaint against Thompson.

Progressive blogger Lane Hudson filed a complaint against Fred Thompson (R-TN) on Monday, accusing the former Senator of violating the Federal Election Commission’s (FEC) “testing the waters” clause. The complaint argues that Thompson is running a full-blown campaign and should be held to the same regulations as the other candidates. ABC’s Jake Tapper writes, “The rule is pretty simple. If you spend more than $5,000 on campaign activities, you’re a candidate, whether or not you’ve officially declared. The question is what constitutes ‘testing the waters’ activity, and what constitutes ‘candidate’ activity.” Within five days of receiving the complaint, the FEC must notify the Thompson exploratory committee and provide it with a copy of the complaint. You can contact the FEC at (800) 424-9530.

UPDATE: Jane Hamsher writes, “I guess we won’t call him ‘The Decider.’”
