To make matters better, many Democrats believe he actually won in 2000, so they wouldn't technically be retreading a loser. Kerry has many Democrats embittered over his poor campaign, even though a good number are still fond of him. Gore is also younger than Kerry, so in 4 years he won't be too aged to seem like a reasonable option.
How true! If the primaries were indeed to boil down to Al Gore vs. Hillary Clinton, the question would be which of the two better represents the positive sides of the Clinton years.
