Those include Michele Bachmann, Herman Cain, Jon Huntsman, Thaddeus McCotter, Tim Pawlenty, Rick Perry, Buddy Roemer, and Rick Santorum.
So now, with just Newt Gingrich, Ron Paul, and Mitt Romney, some say Texas Republicans just don't have much to choose from.
But one local political expert says there is more to talk about in the upcoming Texas Primary than the candidates who are left to fight to be the sole remaining Republican Presidential candidate.
Dr. David Rausch, a local Political Science expert at West Texas A& M University urges voters to weigh in on May 29th in the Texas primary.
He says if there is any concern about low voter turnout, there is not an excuse to bypass voting; May 12th is the first day of early voting for those who are going out of town.
Many folks might still be on vacation after Memorial Day, but they can weigh in before their trip.
Rausch expects a small turnout from the Lonestar state on the Presidential Primary.
"Except for 2008 the Texas primary doesn't have much of an impact on presidential races as some of the other states like Iowa, New Hampshire,"
However, he says that doesn't count out the impact Texas voters can have in other races with multiple contenders.
Those include State Senate, U.S. Representatives, Commissioners, and Supreme Court Justice races to name a few.
"There is a lot more in the primary than just the President; I think if people are not going to vote because of that, they'll miss out on many perhaps more important races."
Rausch says he expects voter turnout for the run off elections in June to be even lower.
The last day to register to vote in the May 29th primary election is Monday, April the 30th.
