To enlarge on Riginslinger's last comment about McCain's chances (or should I say increasing probability to be the next president):

"A Present for McCain as the Other Side Fights"
John Harwood, March 24, 2008; New York Times (Opinion)
"Feuding Democrats have handed Senator John McCain the gift of time." ........
"As the Democratic rivals trade attacks, Mr. McCain, already the presumptive Republican nominee, has crept ahead of both in national polls."

McCain will start his campaign for the presidency "March 31, with a "Service for America" tour, intended to link the senator's biography with his values and policy stances. ....He will address the dominant domestic issue with events in April promoting his economic agenda."
McCain "enjoys robust approval among Republicans (78 percent in the most recent NBC News/Wall Street Journalpoll) and conservatives (68 percent),.... Mr. McCain commands considerable support among independents..."
"For now, Mr. Obama faces continued fallout from the controversy over his former pastor, the Rev. [Wright] and Mrs. Cliton continues to fend off Mr. Obama's attacks on her integrity. If that has not made Mr. McCain the fall favorite, it has left him in a far better position than a month ago."
