Apologies to the late, great crooner Sam Cooke. The Obama campaign has released this video telling voters John McCain isn't up to speed on the economy, the petroleum market, and other issues affecting the middle class.
For those of you who don't recognise the melody, it's a riff on Sam Cooke's great "Wonderful world" love song of 1960.
Also this morning the Republicans invited members of the press corps covering the Denver Democratic convention to a "Happy Hour for Hillary" at a Denver bar. It's part of their effort of late to rub it in Clinton supporters' noses that Joe Biden and not she was chosen as Obama's veep pick.
I don't know how much traction the argument will have, but I do give the RNC props for the wit. (An added bonus: their message slogan on the Denver convention is "A mile high, an inch deep". That's a reference to Denver's nickname, the mile-high city.)
