Williamson County State Representative Dan Gattis will be running for the open State Senate seat being vacated by retiring Republican Senator Steve Ogden of Bryan, Texas. He's launched a new website with announcement video which can be viewed here. Gattis has served in the house for four terms, since 2003 when he was first elected to represent the eastern half of Williamson County. This announcement will create an opening in HD-20 and along with Democrat Diana Maldonado's re-election bid is sure to make the area just north of Austin a hotbed of electoral activity in 2010.
