It’s been nearly 70 years since there last was a presidential election rematch, but it has occurred more than people might think in U.S. history.

NBC News is projecting Rep. Sheila Jackson Lee to win the Democratic primary in Texas’ 18th Congressional District.

Jarvis Johnson, a member the Texas House of Representatives, was at Booker T. Washington High School at 7 a.m. to cast his ballot. However, there was a glitch in the computer’s system that placed him in the wrong precinct. The issue was fixed quickly, and Johnson and his family were able to vote.

Dissatisfied Democratic primary voters in Michigan have cast enough protest votes to deny President Joe Biden two of the state’s 117 delegates.

As the Republican presidential primary intensifies this summer, most White House hopefuls are devoting their time to events in Iowa and New Hampshire, the states that will kick off the nomination process early next year.

(TEXAS TRIBUNE) – Judging from March, the ideological left wing of the Democratic Party in Texas should be inconsolable. Joe Biden practically locked up the Democratic presidential nomination, and progressive candidates experienced electoral drubbings. I feel really good not just about my chances, but the movement overall,” says Mike Siegel, a candidate for Texas' 10th Congressional District. He’s already endorsed at least seven Texas congressional candidates. “The progressive movement is just getting started here in Texas,” Siegel said.

Long lines, a change in polling locations and voting machines forced many to wait hours before they could cast their ballot. He said the county failed to allocate voting machines properly, mismanaged and had faulty equipment. Schecter told KPRC 2 there were only 71 polling locations in precinct 1, 84 in precinct 2, 125 in precinct 3 and 120 in precinct 4. "It’s important to the Democrats to have county-wide voting so we had to agree on all the locations. The Republicans did not want to have county-wide voting and said here’s our map if you want countywide voting, you have to agree to this map,” Schecter said.

Even if one candidate has more delegates than the other, that’s only a “plurality,” not a majority, per party rules. Candidates who earned delegates, but have since dropped out of the race, can try to push their delegates onto another candidate. A candidate needs to earn 2,375 delegates on subsequent ballots to win the nomination. However, having a contested convention is something the Democratic National Committee will do its best to avoid in the coming months. The last time a contested convention occurred was in 1952.

(AP) – Voters in Texas’ Democratic primary ranked health care as the most important issue facing the country, well above climate change, the economy, race relations, foreign policy and many other social issues. Nearly 4 in 10 named health care, an issue that has intensely divided the field of Democratic candidates. More voters in Texas’ Democratic primary said they wanted a candidate who would bring fundamental change to Washington, rather than one who would restore the political system to how it was before Donald Trump was elected in 2016. Climate change, the economy and other issuesRoughly 2 in 10 voters said climate change is the most important issue facing the nation. The survey of 2,982 voters in Texas was conducted for seven days, concluding as polls closed.

As part of our new Ask 2 series, the newsroom will answer your questions about all things Houston. Question: Is it illegal to separate voters by party at the polling sites? This helps explain the long lines for some voters rather than others. For example, if the parties have decided on 10 Democratic voting machines and 10 Republican voting machines at a polling place, the lines will be much longer for one party versus the other if there are many more voters from a particular party. Torres said there are extra voting machines in reserve that are available to help alleviate long lines, but the parties must make a request for them to be deployed.
