An update if you're still interested. David Wallace, mayor of Sugar Land formally filed yesterday. He did this before the party could even meet on talking about the write-in strategy. Sekula-Gibbs is being a team player, saying that she will wait for the party to make a decision and abide by it. The party is none too happy with Wallace. They feel that Wallace is trying to force them into anointing him as the official Republican write-in candidate.
Unfortunately, all of this looks like posturing for 2008 rather than actually winning in 2006.
