The post is here, but I'll go ahead and quote the main info:
Background: In Texas, every State Senate district gets 4 delegates to the state convention. These delegates are apportioned according to the primary votes—the thing for which you'll be casting your ballot on March 4. The remaining 60+ delegates are apportioned among the State Senate districts according to how those districts voted in the 2006 gubernatorial election, and the number of votes that were cast for Democratic candidate Chris Bell. These are the delegates selected in the caucus portion.
What to do: If you want to make sure your vote really counts (in effect, counts twice) for your candidate of choice, you do in fact need to do two things.
- Cast your vote in the usual way.
- At 7:15 PM, after the primaries close, head (back) to your polling place. There, you sign a form that indicates your support for your candidate of choice. You can leave then, or you can stick around and help appoint delegates to the State Senate seat convention.
