(CNN) - John McCain is launching a television ad in the crucial swing states of Michigan and Pennsylvania Wednesday, the latest sign the Arizona senator is gearing up his general election campaign.
The ad, called "Accountable," previously ran in Iowa and promotes the Arizona senator's pledge to lower taxes, make healthcare more affordable, and solve the country's energy problems.
McCain's decision to extend the ad into the more expensive media markets of Michigan and Pennsylvania is the Arizona senator's first shot of the general election campaign, said Evan Tracey of TNS Media Intelligence/Campaign Media Analysis Group.
"The fact that he's expanding into these states is a clear signal that both the general election has begun and fundraising has fattened his campaign accounts," Tracey said.
The McCain campaign is also looking to capitalize on Obama's 9 point primary defeat in Pennsylvania and the little attention the Illinois senator has so far devoted to Michigan. (Obama removed his name from the primary ballot there after the state violated party rules by holding its contest early.)
"What you're seeing is McCain turning up the volume in states that Hillary Clinton won, and clearly trying to capitalize on any negative momentum for Obama in those places," Tracey also said.
