Just passed the half-way mark and Heck maintains his lead. He is up by 2,029 votes, with 56 precincts reporting. The race is still too close to call - 48.3 percent to 47.4 percent, but it is not looking good for Titus.
Heck is expected to make a speech in about 25 minutes. It's unknown whether he will claim victory or wait for more complete results.

As Election Day returns come in, Republican Joe Heck continues to extend his early voting lead over Democrat Dina Titus.
Heck is now beating Titus by just over 1,300 votes, with about 20 percent of precincts reporting.
A tally of early voting returns showed Heck leading by about 400 votes. Initial Election Day returns put Heck 700 votes ahead.
Each update paints a grimmer picture for Titus, a freshman incumbent.
Democrats typically need a strong finish in early voting to secure Nevada elections, and it's unlikely Titus will gain ground in votes cast on Election Day.
Across the country, a number of Democratic House incumbents have lost.
Heck previously estimated he would win the election by less than 2 percentage points.
