Tomorrow (March 2, 2010) candidates from both the Democratic and Republican parties will be trying to win their party's primary elections. The League of Women Voters provides information about the candidates in their online voters' guides available for both Harris and Ft. Bend Counties. Paper copies of the Harris County guide are also available at service points in Fondren Library.
Harris Votes for those residing in Harris County provides a link to "Find your Election Day Poll and View Voter Specific Ballot."
Registered voters in Texas can choose to vote in either primary, just not both.
