Democrat Parker Griffith and Republican Robert Bentley are both 71, both doctors and both running for governor. But Griffith is emphasizing their differences in his race for governor. Griffith says he would repeal the state immigration law that Bentley signed and replace it with a law that doesn't put so many regulations on businesses. He says he would also expand the state Medicaid program under the federal health care law, and he would repeal the Alabama Accountability Act and its private school scholarships. The former Republican congressman from Huntsville says much of his campaign so far has been meeting with Democratic and labor groups to explain why he returned to the party and entered the governor's race. He says it's going well and he's already picked up two labor endorsements.
