Newt Gingrich says President Obama will be undone by three numbers — gas prices, the unemployment rate, and the national debt:
Conventions largely break into two kinds: achievement conventions and accusation conventions.
If you are an incumbent with a good record you run an achievement convention and remind everyone what a good job you have done and why they should reelect you. Mitch Daniels reelection commercials which just listed his achievements without any words for sixty seconds- there were two of them- is a classic example of an achievement campaign.
Obviously the Obama convention cannot be an achievement campaign. The failure of their policies forces them to have an accusation convention. That means accuse Romney of everything. Accuse Ryan of everything you failed to accuse Romney of. Accuse Republicans in general of even more than you have accused Romney-Ryan.
The problem for Obama is that these three numbers are going to be louder than all their accusations combined.
The formula is simple: 8.3 percent plus $3.80 a gallon plus $16 trillion equals failure.
