RESULTS (via Associated Press):
U.S. Senator race- A closely watched matchup is set between U.S. Sen. Ted Cruz and his Democratic challenger, U.S. Rep. Beto O'Rourke.
Cruz and O'Rourke clinched their parties' nominations Tuesday. O'Rourke is raising more money than Cruz so far but remains very unlikely to win in November.
Gov. Greg Abbott also clinched the Republican nomination for governor and enters the general election as a heavy favorite against whoever emerges from the Democratic primary.
Polling places in El Paso and far West Texas closed at 8 p.m. CST, an hour later than the rest of the state.
No Democrat has won a statewide race in Texas since 1994.
Texas Governor race-
The first Hispanic female sheriff in Texas is headed to a Democratic runoff against the son of a former governor in their longshot bid to unseat Republican Gov. Greg Abbott.
Former Dallas County Sheriff Lupe Valdez and Houston investor Andrew White advanced Tuesday from a field of nine largely unknown Democratic primary candidates. The runoff election is May 22.
Texas Democrats haven't won a statewide race since 1994. The party's rising stars in Texas all passed on running for governor after Democrat Wendy Davis lost by 20 points in 2014.
White is the son of former Texas Gov. Mark White, who served one term in the 1980s and died last year. Andrew White is a self-described "conservative Democrat" who has alienated progressives over his personal opposition to abortion.
Valdez would be the first Hispanic and openly gay governor in Texas history.
Texas Land Commissioner - Texas Land Commissioner George P. Bush has won the Republican nomination to keep his post, topping a primary challenger from the right.
Bush, whose grandfather and uncle were president and whose father was Florida's governor, beat his predecessor as land commissioner, Jerry Patterson, Tuesday. The 41-year-old Bush immediately becomes the overwhelming favorite for re-election in November.
Bush began the year with $3.4 million in campaign funds compared to Patterson's roughly $100,000. He won despite campaigning lightly, spending much of his time visiting parts of Texas hit by Hurricane Harvey after his agency was tapped to lead the state's housing recovery efforts.
Patterson criticized Bush for bungling the post-Harvey rebuild and a makeover of the Alamo in San Antonio. Bush was endorsed by President Donald Trump and his son, Donald Jr.
Lt. Governor -
Incumbent Lt. Gov. Dan Patrick won the Republican nomination and will face the winner of Democratic Lt. Gov. nominees Michael Cooper and Mike Collier. Click here to see the latest results from the Democratic nomination race.
Texas House District 46 -
Incumbent State Rep. Dawnna Dukes (Texas House District 46), who spoke with KVUE in Feb. about running for re-election, lost her seat, receiving only 10 percent of the votes. Jose "Chito" Vela (40 percent, 6,209 votes) edged out Sheryl Cole (39 percent, 6,000 votes) by 209 votes in the District 46 Democratic primary nomination.
However, neither candidate received 50 percent of the vote or higher, which means Vela and Cole will have to face-off in a primary runoff election slated for May 22, according to the Texas Secretary of State.
The Democratic candidate who wins the primary nomination would face Republican contender Gabriel Nila in the general election, which will be held Nov 6.
Dukes was elected to the Texas House of Representatives in 1996. The Austin native spent the past 11-terms representing District 46, which encompasses parts of East Austin, Manor, and Pflugerville.
