From NBC's Chuck Todd
Former Speaker Newt Gingrich has decided not to run for president. Gingrich spokesperson Rick Tyler said the conservative icon was given legal advice yesterday that said a presidential campaign would have jeopardized the 527 status of American Solutions should Gingrich had remained involved. Exploring a run for president and continuing his work with American Solutions were legally incompatible and Gingrich chose his American Solutions project. All work that was supposed to go into the presidential exploration has been permanently halted.
While Tyler didn't say it, Gingrich basically was prevented from running for president by John McCain since the McCain-Feingold campaign finance regulations have made mixing political projects very difficult.
