These national polls don't matter.
What matters is that Obama/Biden is ahead in New Mexico, 47.3 to 43.
What matters is that Obama/Biden is ahead in Pennsylvania, 47.4 to 42.4.
What matters is that Obama/Biden is ahead in Michigan, 46.0 to 41.7.
What matters is that Obama/Biden is ahead in Colorado, albeit by the slimmest of margins.
If all of this holds true, they win the election, even without Ohio, Virginia, or Florida. And the McCain/Palin lead in Ohio is less than one point right now, and it's a deadlock in Virginia.
McCain/Palin have a steeper hill to climb in terms of the electoral college.
The Republican ticket naturally has a steeper climb since they have held the office of President the past two terms. Since World War II, no party has won a 3rd consecutive term in the White House with the exception of the Republicans 3 consecutive terms with Reagan and Bush Sr.
Yet, despite that and all the other uphill battles the Republicans face, the election is very close, but with McCain/Palin now ahead of Obama by 3 percentage points in the latest national gallup poll with only 58 days to go before election day. Plus, its the Democrats that actually have to pick up red states in order to win. If McCain/Palin just keeps Nevada, Colorado, Ohio, Florida, and Virginia, they will win the election.
