If Hood is elected, he can work an agreement like Roy Barnes did with the GOP legislature to change the flag.
The Georgia legislature was Democratic when Barnes was governor; I think it only flipped in 2004.
Barnes mustered enough support to change the flag in 2001 (with a Democratic House and Senate) to
this abomination.
Barnes then lost in 2002 (along with the GOP taking the State Senate), and in 2003, Sonny Perdue re-neged on his promise to let the people vote on their new flag. Instead, Perdue, a GOP Senate and a Democratic House rammed through the current iteration (the Democrats would go on to lose the House in 2004).
Lots of voters remained upset with Perdue for lying; I remember all these "Punt Perdue" stickers on street signs in my area with the old flag on them because those Barnes-Perdue flag-issue voters were mad.
