For the first time, Texas is part of the Super Tuesday primary. A legal ruling last week prevented any hurdles.
Texas is a big prize for candidates. The state has 155 Republican delegates and 252 Democratic delegates. That is more than New Hampshire, Iowa, South Carolina and Nevada combined.
Texas Rep. Rafael Anchia said Texas has not been this important in a national election since 2008, when Hillary Clinton and Barack Obama went head-to-head for the Democratic nomination.
"We are going to see candidates come regularly because there is so much at stake – so many delegates up for grabs," said Anchia.
Dallas Republican Party Chairman Wade Emmert agrees.
"We are going to see a big turnout. There will probably be lines to vote so people need to vote early," said Emmert.
The Dallas County elections administrator tells NBC 5 she will be meeting with both of the parties next week to get ready.

"We are looking at maybe tripling the normal turnout," said elections administrator Toni Pippins-Poole.
Pippins-Poole said there will likely be additional polling places, so officials will need more volunteers. She said they have already talked to vendors about more machines.
