A culture of optimism?

As Specter shifts loyalties...

From here: The broader symbolism here is that it’s another sign that Barack Obama’s first two years may not look like Bill Clinton’s. In 1993-94, Clinton’s approval ratings sagged, his party lost special elections everywhere, and conservative Democrats were switching to the GOP. Obama’s approval ratings are high and holding steady, Democrats remain far more popular than Republicans, Democrats held the first special election, and now they’ve picked up a party switch. It’s still early, but Obama is starting to build a self-sustaining psychology of success.
