EL PASO, Texas—Former President Bill Clinton wants Texans to vote for his wife, twice.

Clinton swept across Texas on Saturday, rallying thousands of voters for Democratic presidential candidate Sen. Hillary Rodham Clinton at events in Corpus Christi, Killeen and El Paso.

Bill Clinton told supporters at an early morning rally in Corpus Christi that while it’s important for them to vote for his wife in early voting or on March 4, they can’t forget to participate in the precinct caucuses.

Those caucuses, he told the crowd, will decide 35 percent of the states’ 228 delegates.

Texas has a hybrid system—part primary, part caucus—that awards 228 delegates in all.

Primary voters will decide 126 delegates in 31 state senate districts. About half the districts have four delegates, and others range from two to eight delegates. The former president also repeated his assertion that Hillary Clinton must win Texas and Ohio on March 4 to win the Democratic nomination.
