Veteran GOP strategist Mike DuHaime will manage the National Republican Senatorial Committee’s independent expenditure arm for the 2010 cycle.

DuHaime joins the committee after working on the successful 2009 campaign of New Jersey Gov. Chris Christie (R). He previously was political director for the Republican National Committee and served on the presidential campaigns of former New York Mayor Rudy Giuliani (R) and Sen. John McCain (R-Ariz.). DuHaime was regional political director for President George W. Bush’s 2004 re-election campaign.

Selecting an operative to run independent expenditure operations is a particularly important decision for the campaign committees; they determine where and how to spend precious resources, and staffers at the committees are prohibited by law from being involved in those decisions.
