Six months after U.S. Rep. Parker Griffith switched to the Republican Party, he's facing a tough primary fight and questions about his political stripes.
He's been branded a "flip-flopper" by his opponents and has had to invest more than $250,000 of his own money.
Next Tuesday's primary will be the first real test as to whether the party switch bothers voters as much as it has seemed to rankle north Alabama GOP leaders who doubt his motives for switching parties.
When the 67-year-old physician switched parties last December, he said he was doing so because of concern about the Obama administration's health care overhaul. But critics say it had less to do with philosophy and more about political survival in an increasingly Republican-leaning district.
