Democrats hope to break a losing streak in statewide races that dates back to 1994. Many Republicans say they want to show their steadfast support for President Donald Trump.

5 p.m. North Texans are packing the polling places as two hours remain before they close at 7 p.m. In Dallas County, if you're getting the Republican Party ballot, you have to consider 36 races and 11 proposition. The Democratic ballot has 90 races and 12 propositions.

A bruising battle for Texas Senate District 8, a Collin County Senate seat in which candidates Phillip Huffines and Angela Paxton face off in an expensive campaign. Huffines, a real-estate developer and former chairman of the Dallas County Republican Party, gains support from business-minded conservatives. He's the twin brother of state lawmaker Don Huffines. Paxton, a guidance counselor and wife of Attorney General Ken Paxton, received help from party members supportive of faith and values. An estimated $10 million spent from both candidates to fuel their campaigns.

6 p.m. This election is more important than previous mid-term primaries because of all the retirements and resignations we've had in North Texas. There are a number of open seats from Congress to Legislature.

WFAA will have political analysis from across the state starting at 7 p.m. Watch the Facebook Live feed on WFAA’s Facebook page.

7 p.m. Polls have closed in parts of North Texas. Texas Gov. Greg Abbott is unchallenged on the Republican side, but for the first time in years, there could be an interesting fight for the Democrats.
