Message discipline 101: If you’re going to drop five ads in a day, they probably shouldn’t be on five different subjects. Thus far, we’ve had one hitting Biden for his tribute to higher patriotism through confiscatory taxation; one on The One’s Fannie Mae connections; one on his general gutlessness when it comes to voting on bills that put him in a difficult political spot; one on his willingness to sit down with the heir apparent to Castro and Che Guevara; and finally a meat-and-potatoes economy spot. Which, let it be noted, goes much easier on Obama than Obama went on McCain when the subject of outsourcing came up last week.

Exit question: Is it worth using Romney as a surrogate in Michigan on the economy or is there just too much filthy-lucre baggage to overcome at the moment?
