Today's Zogby poll has Bush at 48% and Kerry at 46%. Both gaining a point compared to yesterday.
With an eye to the Polling Report analysis I linked in above, there's good news and bad news in the internals.
Good news: "Zogby said only one in five of the undecided voters felt Bush deserved a second term in the White House. "These are the most important people in America today. Well over 90 percent of undecideds tell us they're going to vote. And only 20 percent say the president deserves to be re-elected," he said."
These numbers confirm the PR analysis: the undecideds are likely to break against the incumbent. In this case, it appears, quite massively, and on a high turnout.
Bad news: "The number of undecided voters in the poll fell to 4 percent. [..] Bush reached 50 percent in the last of the three days of polling on Saturday that went into the survey."
The idea in the PR analysis being that if an incumbent is at or over 50%, he's quite safe. The undecideds may break to Kerry massively, but if there's only 4% of them left and Bush gets 50% even without them, that doesn't do us much good.
