From Anna Tinsley of the Ft. Worth Star Telegram:
The main question in [the Texas primary today] is likely, "How big will the Ron Paul effect be?"
Political observers estimate that Paul, a retired doctor with a loyal following, may pull anywhere from the upper single digits to somewhere in the double digits Tuesday.
His supporters are likely to make a big stand in his home state, especially since they want to be a force at state GOP conventions nationwide -- as they were during his 2008 presidential bid....
Romney has 1,084 delegates, according to estimates by The Associated Press; 1,144 are needed to clinch the nomination.
He could pick up those votes Tuesday in Texas, where 152 are up for grabs.
[Says Allan Saxe of the University of Texas], "It's likely that Ron Paul will get a large percentage but not enough to embarrass Romney."
