The hiring underscores awareness that Trump’s team needs more manpower as the media mogul rises in national polls. Former Americans for Prosperity operative Corey Lewandowski serves as campaign manager.
A Quinnipiac University poll released Thursday confirmed Trump as the leader of the Republican presidential field, with 20 percent support, followed by Wisconsin Gov. Scott Walker with 13 percent.
Glassner joins the campaign just a week before Trump will appear in the first Republican primary debate, to be held in Cleveland.
Glassner served as a top aide to Palin during the 2008 White House race and a senior adviser to the campaign of President George W. Bush in Iowa in 2000. He started in politics as an aide to then-Sen. Bob Dole (R-Kan.).
“I am proud and honored to have the opportunity to work with Donald J. Trump, the very definition of the American success story,” Glassner said in a statement. “Mr. Trump has set the standards of excellence in many arenas, including real estate, sports, and entertainment — and now, in American politics.”
Trump signaled his fondness for Palin this week when he said he would “love” to appoint her as a member of his cabinet.
