Senate Majority Leader Harry Reid, who faces a potentially tough race even as Republicans are yet to settle on one challenger, launched the first two television ads of his re-election campaign today. Both are upbeat, one-minute spots that invoke his clout as the Senate's top Democrat in making the case for another term next year.

In "Hard Work," Reid speaks to camera about his humble upbringing, as a narrator notes that Reid is working as Senate leader to "get Nevada's economy back on track." This spot is running in the Reno market.

In "Nevada Jobs," which is running in the Las Vegas market, MGM Mirage CEO James Murren testifies to Reid's efforts to save the City Center project. "There's nobody else who could have done it," he says. The spot ends, as does the first, with the slogan, "Harry Reid: Determination that makes a difference."

Reid raised $2 million in the most recent fundraising period, and has more than $8 million in the bank. Vice President Joe Biden is set to raise money for his former Senate colleague tomorrow in Reno.
