McCain campaign says it's saving the best for last

Marc Ambinder has been talking with contacts he maintains in the Republican campaign. Apparently, as we might have anticipated if we gave it thought, there is a game plan for the last 10 days:

McCain advisers say they're saving their best material for the last ten days of the race, when, the campaign hopes, three quarters of the remaining undecided voters will make up their minds, and their minds will be concentrating on Barack Obama. When the urgency of the presidential election impresses itself, the hope is that these voters will swing back to the familiar, rather than the unknown. The last ten days, according to a McCain aide, are when the "imponderables" come into play.

Obviously, they do not plan to go quietly into that good night; they're going to throw everything, including the kitchen sink, at Obama. I trust that John McCain is not the only candidate who plans to propose "imponderables" during the campaign's last 10 days.
