" While I don't think this is necessarily some trick up McCain's sleeve to sound statesmen-like and get one on Obama, I think its a little strange to "suspend" your campaign."

Forgive me if I sound cynical, but the first thing that popped into my mind when I heard McCain's call for him and McCain to "suspend" their "campaigns" was,
"Yeah, sure. You and your opponent suspend your OFFICIAL campaign appearances and ads for a couple crucial weeks -- while the 90% right-wing-dominated radio talk shows and the TV "pundits" (working for media companies owned by defense corporations, oil corporations, big pharma, etc.) and the unofficial 527s continue their propaganda unabated.
How conveeeeeeenient!
