Does the McCain Campaign Have a Reason to be Unusually Upbeat?

An article on MSN report that the McCain campaign is unusually upbeat just days before the election. Do they really have a reason to be? With only five days until Election day, John McCain's campaign aides seem to be in a happier mood than they have in quite some time. For the last few days, the campaign has been increasingly buoyed by what it says has been improvement in it's internal polling of 14 battleground states. Even McCain himself is upbeat. " He's been happy for the last few days," says one aide. " That's a change." What to make of this? Because, still the landscape looks pretty bleak. A flood of public polls show that McCain is down in several important, traditional, Republican States. The News organizations and ysts that have reported and sifted the numbers guess that, at the moment, Obama would garner upward of 310 electoral votes by winning not only all the states that John Kerry won, but also Ohio, Virginia, and several other states that went for Bush in 2004. The article claims that the mindset of the McCain campaign on a continuum that sketches from deceit.( know they are losing, and play acting) to drudge like self delusion. ( clutching at any glimmer of hope).....Does it seem that the McCain campaign is somewhere between self delusion, and truth?
