Because of redistricting it's possible that your voting precinct has moved, or you've been moved out of your voting precinct.
Harris County Clerk Stan Stanart estimates 20 percent of voters in the county have been affected by redistricting.
"1.956 million voters, that's how many are currently registered in Harris County. In an election year when the redistricting process may have changed your voting location on election day, I strongly encourage everyone to go vote early."
Early voting begins on October 22nd and runs through November 2nd. ClearChannel donated the use of two dozen billboards along area freeways to promote early voting Harris County Commissioner Steve Radack says the signs will go up in English, Spanish, Vietnamese and Chinese.
"We have 37 early voting locations here in Harris County, spread all over the county. People can vote at any location, it doesn't matter where they live, as long as they live in Harris County we welcome them to any of the 37 locations. I want to emphasize how important it is, particularly in the general election, to vote early. There will be long lines."
Nearly 700,000 people in Harris County voted early in the 2008 presidential election. More information on voting locations, dates and times is available on the Harris Votes website.
