Republican presidential nominee Donald Trump faces a formidable challenge tonight when he and Democrat Hillary Clinton go head to head in a third and final televised debate. Mr Trump must try to reverse momentum in an election that polls show is tilting away from him.

Donald Trump's faltering campaign and the open warfare it's triggered within his party are bound to hurt other Republican candidates. The question is, how much? Democrats went into this election cycle optimistic about taking back some of the many legislative chambers they lost in 2010 and 2014. Trump's problems give them a real chance.

For a man who built his unlikely political rise on his hardline opposition to immigration, Donald Trump hasn’t talked much about the issue lately—not since a surprise trip to Mexico and a scorching speech in Arizona in late August that put to rest speculation he was “softening” his tone. The issue hardly got a mention in the first two presidential debates, despite Trump's farfetched promise to build a wall along the southern border and to make Mexico pay for it.

As he completes his third term in the House, Rep. Joe Heck has established a solid, if unspectacular, record as a relatively moderate Republican who has advanced in the GOP caucus while scoring some modest legislative successes.

Catherine Cortez Masto’s time as a public servant over the last three decades reflects a low-key yet professional executive branch official who worked well with most. .

The Republican Party’s presidential candidate refers to Mexicans as rapists and wants to build a wall along the entire southern border. The Democratic candidate for Senate in Nevada is Catherine Cortez Masto, a Latina whose grandfather came to the U.S. from Chihuahua, Mexico. And a Democratic House candidate is Ruben Kihuen, who came to the U.S. at age 8 from Guadalajara, Mexico.

As a state that has been built on the gaming industry and tourism tied to it, Nevada knows odds. And the odds are now against Donald Trump here. Stylistically, Trump would seem a natural fit for the Silver State’s pronounced anti-establishment streak. When Senate Minority Leader Harry Reid ran for re-election here, he proclaimed he was "independent, just like Nevada.” Meanwhile, non-college-educated white voters exceed the share of white voters who are college-educated — a favorable dynamic for Trump, who has consolidated white working-class support across the country.
