Former Republican Sen. Lincoln Chafee will attend the Democratic National Convention in Charlotte in September, WPRI reports.

Chafee is now the independent governor of liberal Rhode Island, and has been drifting away from the Republican Party since at least 2006, when he lost his re-election bid for the Senate. (In 2004, he withdrew his support for President George W. Bush's re-election.) Chafee backed President Barack Obama's 2008 run, and is a co-chair for his campaign.

The Republicans have their own convert to brag about, however—former Alabama Democratic Rep. Artur Davis. Davis, who backed Obama at the 2008 Democratic convention, will be a headliner at the Republican National Convention in Tampa this year.
