What Mac Doesn't Get About Obama

Mark Halperin writes in Time that John McCain is underestimating several challenges ahead of him:

• The “astonishing enthusiasm” Obama inspires, compared to the respect McCain enjoys
• How “major league” Obama’s infrastructure is compared to his own
• The difficulty of running against Bush and Barack at once. He’ll have to knock the president in front of Republicans

• How little Americans care about foreign policy when the economy is down
• How much even the GOP dreads another Bush term
• The media perception that Mac is running for another Bush term
• That his lack of financial message makes Obama look like an economics genius
• How old he looks on the stump, and how how odd that makes his message of change look
• How boldly Obama is going to run, not walk, to the center now
