So what happened to give McCain a one-point lead in the one-day polling on Friday? It was a day of consolidation for him, too. He had been losing support among key groups and began to regain some of his own base. He now leads by 21 points among NASCAR fans, 9 among investors, 6 among voters in armed forces households, and 2 among voters over 65 years old.

Remember, as I said yesterday, one day does not make a trend. This is a three-day rolling average and no changes have been tectonic. A special note to blogger friends: calm it down. Lay off the cable television noise and look at your baseball cards in your spare time. It is better for your (and everyone else’s) health.
