"It took thousands of men to build Hoover Dam and modern Nevada. But it only took two men to help tear down its economy," says the narrator in the commercial, which begins running Friday on cable television in Las Vegas, according to an RNC official.
Nevada currently has the highest state unemployment rate in the nation at 14 percent. The state's unemployment rate stood at 9.6 percent when Obama took over in the White House at beginning of last year.
Thursday night Obama headlined two campaign events for the top Democrat in the Senate, who polls suggest faces a difficult re-election this year as he bids for a fifth term in office. A Reid campaign spokesman says two events at the Aria Resort and Casino in Las Vegas were expected to raise $800,000, according to a pool report.
The president called Reid "a man of principle. He is a straight shooter. He is a man of his word," as he urged the estimated crowd of around 3,000 to send Nevada's embattled senior senator back to Washington.
Obama mocked Reid in jest, saying Reid is soft spoken.
"Harry is always in a tough race. He's just not a flashy guy. You'd think that since we're in Vegas, somebody could give him some tips," said Obama.
But the president said Reid is a fight who knows how to win.
"Anybody who knows Harry knows he is made of strong stuff. This is one tough guy," said the president. "He does not give up, he does not give in, he keeps on fighting and he outlasts them."
The RNC ad has a different message, blaming Obama and Reid for Nevada's extremely difficult economic times.
"Barack Obama and Harry Reid. They've dealt bailouts, handouts, and takeovers, giving us a $1.5 trillion deficit, a $13 trillion national debt, 14 percent unemployment for Nevada. When it comes to Nevada's economy, Obama and Reid are a bust," ads the narrator in the commercial.
At the campaign event, Obama mocked Sharron Angle, Reid's Republican opponent. He said Angle wants to phase out Medicare and Social Security, end education funding, and called the compensation fund for BP "a slush fund," a statement Obama said Angle's campaign later said was a kind of mistake.
Angle made the comments Wednesday in an interview on a radio program. Thursday Angle walked back the comments a bit, saying she shouldn't have used the term "slush fund" and saying she supported the BP escrow fund.
"I'm sure she meant slush fund the nicest possible way," the president joked, to much applause from the audience, some of whom yelled that Angle was a "lunatic" and an "idiot," according to a pool report.
"Basically, you have President Obama and Senator Reid together in a giant glass house raising money to throw rocks at Sharron Angle during a time when 192,000 Nevadans are unemployed," said Angle spokesman Jerry Stacy, prior to Thursday night's event.
"Harry Reid knows he can't win by running on his own dismal record, so he is attacking Sharron Angle in an attempt to distract voters from who he is. He's not getting away with it that easily - Nevadans are tired of Harry Reid's rubber-stamping higher taxes and irresponsible spending policies in Washington, and it's time for him to go," added Stacy.
Angle beat 12 other candidates in the June 8 GOP primary to capture her party's Senate nomination. Angle, a former Nevada state lawmaker, enjoys strong support from many in the Tea Party movement.
