A landslide is available to us Dems if we work hard toward November

Check out the Gallup polling that shows what the potential is when a Democratic Congress and a Democratic president manage a success or two: suddenly a six-point lead, where before the picture looked gloomy.

Imagine the polls if President Obama's cautious handling of the BP oil disaster finally results in a secure shutdown of the well. This is within reach -- keep fingers crossed to prevent the laws of physics and geology from combining in a new explosion of the well. Polls now may show the public is dubious about the president's handling of the crisis. That will change bigtime when the well is capped.

Our job is to remain committed to work hard, and to avoid overly pessimistic moods.
