That's the number of Texans signed in as delegates to the 2008 state party convention, and each indicated a presidential preference.
Those numbers were 4,144 for Obama, 3,088 for Clinton, and seven undecided (you gotta love it).
The percentages are 57.3% Obama, 42.7% Clinton. That translates into 24 Obama delegates to the national convention, in Denver in August, and 18 for Hillary. Each camp gets three alternates.
Update: Trailblazers has the full and final tally... Obama 99, Clinton 94.
