The daughter of the state's outspoken late Gov. Ann Richards made a Web video wishing her mother were still alive to fight for Clinton.
"After all, Ginger Rogers did everything Fred Astaire did -- she just did it backwards and high heels," the former governor is seen saying on the video.
The push for the state's female and Latin voters is critical for Clinton, but it may not be enough, as Obama also has been courting Hispanic voters.
"Barack Obama's going to have made inroads with Latinos," said ABC News political contributor Matthew Dowd. "And his huge support among African Americans is going to be more than enough to compensate for her support among Latinos."
And Texas is complicated. The delegates are awarded based upon who showed up during the last election, and African Americans showed up in larger numbers than Latinos. And part of the voting is determined by caucusing -- a format that has favored Obama so far.
Texans cannot escape the race. It is all over the airwaves. Obama and his allies -- unions and outside groups -- are outspending Clinton by about two to one on television.
