Halperin projects the electoral college

Mark Halperin writes this morning that Obama's path to 270 is easier to see than McCain's:

Based on interviews with political strategists in both parties, election analysts and advisers to both presidential campaigns — including a detailed look at public and private polling data — an Obama victory with well over 300 electoral votes is a more likely outcome than a McCain victory.

Halperin believes that Obama starts with a "seemingly impenetrable" base of 291 electoral votes. He cites Obama's funding edge, superior organization, and poll position as reasons that Obama can win most of the remaining toss-up states:

Obama could take all of the still contested battlegrounds, giving him nearly 400 electoral votes, and a significant multi-regional mandate.
