Until now, voters in Virginia, New Jersey and Alabama have had all the fun with big elections that gripped the nation, altered the U.S. Senate and provided an appetizer for what many expect to be a tumultuous 2018 election cycle nationwide.

But now it’s the Lone Star State’s turn to join the mix with the earliest primary elections in the nation — and with plenty at stake.

On March 6, Texas voters will decide who will carry the Democratic party’s mantle into the battle for governor and a slew of other statewide offices in the nation’s biggest GOP stronghold, remake the state’s congressional delegation with eight new members likely determined during the primary in heavily gerrymandered districts, and test U.S. Sen. Ted Cruz in his first re-election since his stunning victory in 2012.

What the turnout looks like in the Texas primary will tell a lot about what lies ahead for Republicans and Democrats in 2018, said Cal Jillson, political science professor at Southern Methodist University. If there is big minority voter turnout — traditionally low in gubernatorial cycles in Texas — it could signal that the higher-than-expected turnout in last month’s Senate race in Alabama is a developing trend nationally that could have lasting impact. Similarly, what turnout looks like for suburban white women who helped elect Donald Trump in 2016 will tell Republicans a lot. If they come out in the GOP primaries, they could again help Republicans comfortably carry the day.

But there’s not much time for any of it. Early voting starts Feb. 20 — six weeks from Tuesday. And for thousands of Texans in the military and overseas, they could be filling out ballots in as little as two weeks to make their choices. Military and overseas ballots must be out by Jan. 20, according to the Texas Secretary of State’s office.

In 30 of the nation’s 50 states, primaries are from June to September. Texas is one of only two states that have March primaries. Illinois holds its primaries on March 20.

“It makes it difficult for voters,” Jillson said. “You’ve just come out of the holidays and you look up and you are just a few months before Election Day.”

That has campaign teams in Texas working at warp speed trying to gain name identification at a time many Texans are still taking down Christmas decorations.

“Everything is happening now,” said Donna Stanart, campaign manager for David Balat, one of nine Republicans running in the 2nd Congressional District, which runs from west Houston and wraps around to Atascocita and Humble in northeast Harris County.

Adding to the pressure is the fact that in some Republican primary races, nearly half the votes will be cast during early voting. That means really seven weeks for candidates to find a way to stand out.

Jillson said the early primary benefits incumbents because they are typically better known and have more money. But in crowded fields with mostly unknown candidates, the next nine weeks is an exercise in branding and building name recognition through any means possible.

“Somehow you have to embed your name in peoples’ minds,” Jillson said.

March 6 isn’t likely to be the end of the primary for many races. In contests with a lot of candidates and no clear favorite, a run-off election becomes increasingly likely. If no candidate gets above 50 percent, a runoff election is set for May 22.

Perhaps the most notable race is for governor. Texas has 10 Democrats running to determine which will take on Gov. Greg Abbott, who himself faces minor opposition from two Republicans in the GOP primary. Dallas County Sheriff Lupe Valdez and Andrew White, the son of former Gov. Mark White, are two of the best-known names in the race for Democrats.

But this election year will bring big changes in Congress for Texas.

Statewide, eight congressional races are open seats, meaning there is no incumbent seeking re-election, after an usually high amount of retirements. Texas has not lost more than eight sitting congressman in one year since 1996, when nine incumbents retired or were defeated for re-election.

In San Antonio, U.S. Rep. Lamar Smith is retiring after 30 years in Congress, creating a competitive race for the first time in memory in District 21, a district that stretches from San Antonio to Austin. Eighteen Republicans and four Democrats have filed to run for Smith’s seat.

One of the most watched races in Texas will be for the U.S. Senate where Cruz, finishing his first term, faces four lesser-known Republicans in a primary. On the Democratic side, El Paso Democrat Beto O’Rourke first needs to get through a primary with two other Democrats to get to the highly anticipated battle with Cruz.
