Obamacare. It's as simple as that.
According to Griffith (in the story linked above) . . .
"I believe our nation is at a crossroads and I can no longer align myself with a party that continues to pursue legislation that is bad for our country, hurts our economy, and drives us further and further into debt."
. . .
"I want to make it perfectly clear that this bill [Obamacare] is bad for our doctors. [He might know what he's talking about here - he is a doctor.] It's bad for our patients. It's bad for the young men and women who are considering going into the health care field."
Who's next? Bart Stupak?
Come on in conservative/Reagan Democrats. The water's fine.
