Rep. Parker Griffith (D-AL R-AL) might be facing some opposition on right after his party switch, but he is being welcomed to the GOP by one top name: Sarah Palin.
Some of these stories are hilarious when read years later.
From a snippet of his Wikipedia page:
A lifelong member of the Democratic Party, while serving in Congress, at the urging of Republicans he switched parties on December 22, 2009.[1][2][3] He ran for re-election in 2010 but was defeated in the Republican primary by Mo Brooks.
