The Deadly Final Attack...

It looks like the deadlier final attack might come not from John McCain, as advertised, but from Barack Obama, with his McCcain-will-cost-you-more blitzkrieg. McCain's already on extremely weak footing regarding the economy. 

By eliminating McCain's one economic trump card, that he is a tax cutter and Obama a tax-hiker, Obama's pounding on those coffin nails.

This is why the "Barack Obama is lying to voters and is a dangerous terrorist pal who can't be trusted" response is coming from the McCain campaign; their only hope is to erode trust in Obama's attacks the way Obama eroded trust in mccain's attacks. 

One worry for Republicans is that McCain has already gone too negative too quickly; you never pull out the strongest punches against your opponent until the very end; it's hard to get tougher than the kindergarten ad... or over-the-top statements about Obama not being fit to lead.
