Jeb Bush in 2008?

Brendan Miniter has written a column for the Wall Street Journal saying that maybe we shouldn't write off President Bush's younger brother as a candidate in 2008.

Perhaps the most compelling reason why Jeb Bush shouldn't be written off just yet came Friday with the Labor Department's latest jobs numbers. With some 200,000 net new jobs created in July and some 3.5 million new jobs over the past two years, it's getting harder to deny we are now in the midst of a Bush boom. . . . . If we get three more years of solid economic expansion, voters may decide that keeping a Bush in the White House is good for their wallets. After all, the Bush tax cuts are now set to expire in the middle of the next president's first term.

He makes a decent argument, but I'm not buying Jeb Bush as a candidate for a few reasons.
1. He has emphatically declared that he would not run.
2. His wife has stated she doesn't care for the loss of privacy as a governor's wife.
3. His daughter has had well documented problems with substance abuse. Does anyone think the left wouldn't stoop low enough to exploit his daughters problems?
