Vice President Joe Biden and actress Eva Longoria urged Democrats to get out and vote during a rally Saturday at a Las Vegas union hall aimed at shoring up sagging statewide turnout by party members ahead of Tuesday's election.

Biden and the former "Desperate Housewives" star both urged Latinos to support state lieutenant governor candidate Lucy Flores, and Biden, in more than 30 minutes of personal recollections and political exhortations, made a declaration for the party faithful.

"We've got three days," Biden said. "If we vote, we win. If we don't, we lose."

Flores, a state assemblywoman, told the audience of perhaps 300 people at Plumbers and Pipefitters Joint Local 525 that she knew she'd been outspent in her race against Republican state Sen. Mark Hutchison to replace the term-limited Brian Krolicki.

Campaign disclosures showed Flores raised and spent about $700,000 on her campaign, while Hutchison spent about $2.4 million.

"Despite all that money, he has not been able to pull ahead in the polls," Flores said. "We can sit here and think that everything will be OK. We're not OK unless you vote."

Almost 25 percent of registered voters in Nevada have voted already, including 7 percent more Republicans than Democrats, according to figures released after early voting ended Friday.

Longoria is co-founder with Democratic National Committee finance chief Henry Munoz III of a political group called Latino Victory Project. Both appeared on the stage with Flores and Biden to call Latino issues American issues.

Biden, Longoria and Munoz also urged support for Democratic U.S. Rep. Steven Horsford, a first-term congressman whose re-election campaign against challenger GOP state Assemblyman Cresent Hardy in Nevada's 4th congressional district has seen a recent wave of interest group spending.

The conservative group Crossroads GPS has poured hundreds of thousands of dollars into ads linking Horsford to President Barack Obama, whose popularity is at near-record lows.

"He might have the Super PACs," Horsford told the crowd. "But I have you."

U.S. Rep. Dina Titus, D-Nev., also urged the party members to vote. Titus is expected to face little challenge from Republican challenger Dr. Annette Teijeiro in a heavily Democratic district.

"We've got three days," Titus said. "Three days to get it done."

Biden talked about the power of the Latino vote. He promised that President Barack Obama would act on immigration reform — a touchstone issue for Hispanics nationwide — even if Congress remains deadlocked.

"By the way," Biden said, "the president is going to act on this if they don't."

The campaign stop was Biden's third this year in Las Vegas, and his third stop of a day that began in San Diego and included a visit to a high school in California's San Bernardino County.
