All too often, candidates just hope bad behavior in the past doesn't get exposed, and go on and run anyhow. That's the problem.

Frankly, I want all Democratic candidates to be people of strong, positive character. That's what I expect of them. Sadly, I'm too often disappointed.

Every candidate should look at his or her past closely, and measure his or her own character carefully. If there's something in the past that might prevent getting elected, the appropriate thing is to decide whether to run. Every candidate should assume that past behavior will come out if it is negative. If such behavior would prevent getting elected, perhaps not running is the best choice.
