Quadrennial presidential candidate Ralph Nader hit the airwaves Tuesday with two new radio ads -- his first advertising buy of the election season -- to decry the financial bailout and offer himself as an alternative to the two major-party candidates.

"How much more political garbage will you take from the Republicans and Democrats?" the ad’s narrator asks. "On November 4, you have a choice: the bailout boys McCain and Obama, or Ralph Nader, the man who for more than 40 years has stood with you against Wall Street crime and Washington corruption."

The 30- and 60-second spots are running in 22 markets in 12 states -- including battlegrounds like Colorado, Ohio, Pennsylvania and Virginia. But Jason Kafoury, Nader’s national campaign coordinator, insisted that Nader is not trying to run as a spoiler.

The decision on where to run the ads was based on where the campaign has the strongest numbers. Kafoury pointed to a CNN/Time poll [PDF] released today that shows Nader with 3-4 percent support in Nevada, Ohio and Pennsylvania.

And Nader is siphoning most of those votes from John McCain, not Barack Obama, Kafoury added.

"Independents that would vote for McCain are breaking towards third-party candidates," Kafoury said.

Nader, 74, has run in four consecutive presidential elections. In 1996 and 2000, he was the Green Party's nominee; in 2004 and this year, he has run as an independent.
