Griffith, who captured the seat in a close 2008 open seat contest, will become the first Republican to hold the historically Democratic, Huntsville-based district. A radiation oncologist who founded a cancer treatment center, Griffith plans to blast the Democratic health care bill as a prime reason for his decision to switch parties—and is expected to cite his medical background as his authority on the subject.
While the timing of his announcement was unexpected, Griffith’s party switch will not come as a surprise to those familiar with his voting record, which is one of the most conservative among all Democrats.
He has bucked Democratic leadership on nearly all of its major domestic initiatives, including the stimulus package, health care legislation, the cap-and trade energy bill and financial regulatory reform.
