Candidates Counting On Texas Turnout

Texans probably will vote in record numbers today in the state's first presidential primary election that matters since 1988.

Texas' March primary usually comes after the Democratic and Republican nominees have been sewn up. This year, Democrat Barack Obama is counting on a Texas victory to widen his lead over Hillary Rodham Clinton and perhaps force her out of the race. Clinton is betting that winning the second-largest U.S. state will spur a comeback.
