Sean Magers, who had worked for Alabama Rep. Parker Griffith since before the freshman Congressman came to Capitol Hill, resigned his post as the press secretary on Wednesday afternoon, one day after Griffith switched parties and joined the Republican Conference.Magers exit may be the beginning of a staff overhaul in Griffith’s Congressional office as he begins his new life as a Republican Congressman. Griffith has already lost most of his political campaign team in the last 24 hours, including his pollster, media consultant, mail consultant and fundraising consultant. His Alabama-based general consultant, Main Street Strategies, is staying with him.Magers began working for Griffith in April of 2008 when the former Democrat jumped into the open seat race to replace retiring Rep. Bud Cramer (D). Magers served as Griffith’s communications director on the campaign and stayed on to serve as press secretary for the Congressman after the election.Mager said he would be “pursuing other opportunities in D.C.— but declined to comment further on his exit from Griffith’s office.
