Two fiercely competitive congressional contests are the races to watch Tuesday in Nevada.
Voters will choose who should compete for the open seat held by Republican Rep. Joe Heck and who should try to reclaim GOP Rep. Cresent Hardy's seat for the Democrats.
Hardy's district has a solidly Democratic registration advantage.
He faces three well-funded Democrats in the race for the 4th Congressional District, which includes North Las Vegas and rural, central Nevada.
State Sen. Ruben Kihuen, former Assemblywoman Lucy Flores and philanthropist Susie Lee are trying their hand for the Democratic nomination.
The race has attracted attention from political power players including the President Bill Clinton and Sen. Harry Reid, who have all endorsed Kihuen, and Bernie Sanders, who is helping Flores.
