R. Emmett Tyrrell makes a prediction:

Actually, the economy is chugging along in a healthy and protracted period of growth. For the past five years, per capita gross domestic product has grown at 11%. We are living through a vast global economic boom, and the Democrats seem completely unawares. In 2008 their presidential candidate will be moaning that we have lost a war and are economically in a hell of a mess. The Republican will only have to point to a healthy economy and the success of General Petraeus's splendid army to win. Then the Democrats will whine that the Republicans stole the election from them. That is my prediction, and I base it on the evidence.
