2008 Texas Democratic primary and caucuses were a series of events to determine the delegates that the Texas Democratic Party sent to the 2008 Democratic National Convention . Delegates were selected using results from two sources : the Texas Presidential Primary held on March 4 by the Secretary of State of Texas 's office , and a series of caucus events held between March 4 and June 7 by the Texas Democratic Party . The indecisive results of Super Tuesday , and the fact that Texas had the largest number of delegates among the states remaining on the Democratic primary calendar , resulted in the Texas primary receiving significant attention from both the Hillary Clinton and Barack Obama campaigns
