A new ad from the RNC touts McCain as stronger on the environment than Barack, who is good at saying no to ideas like nukes and encouraging the sourcing of new supplies.

The Republican National Committee is spending $3.4 million on television ads in four swing states blasting Barack Obama’s energy policy, according to a campaign finance report filed Monday.

The 30-second ad is part of an independent campaign on behalf of Sen. John McCain. It says McCain is “pushing his own party to face climate change,” and contrasts the presumptive GOP nominee’s energy stand against Obama’s.

But don't feel bad for Barack. He'll get party help as well.

The $3.4 million buy is substantial. But it is likely only the ante for the RNC and the Democratic National Committee. The DNC alone spent more than $100 million in 2004 on behalf of Sen. John Kerry’s presidential run.
