Who Can Vote In The Runoff?

The Secretary of State is on top of the situation:

The Texas Secretary of State's office wants voters to know who can participate in the Republican and Democrat primary run-off election.

"A number of media outlets across the state have incorrectly reported that only those individuals that cast a ballot in the March 9th primary elections may vote in the April 13th run-off election," spokesperson Jennifer Waisath said. "Even if you did not vote on March 9th, all registered voters can still participate in the run-off elections on April 13th."

Who can vote in the April 13th run-off election?

• Texans who voted in the March 9th Republican primary can cast a ballot in the Republican run-off, and Texans who voted in the Democratic primary can cast a ballot in the Democratic run-off; or,
  
  
• Registered voters who did not participate in either of the parties' March 9th primary elections may choose to vote in the Republican or Democrat April 13th run-off election, but they cannot vote in both run-offs.

Early voting for the April 13th run-off begins today (April 5, 2004) and runs through Friday, April 9th. Since Friday, April 9th is Good Friday, if county offices are not regularly open for business on Good Friday, then the county is not required to conduct early voting on that day.

From the 2006 calendar in The Rules of The Texas Democratic Party (.PDF) you can even register to vote for the runoff until Tuesday March 13th.
