This could be just what the Democrats need without knowing it.

Brown isn't new. He's a state senator. This is a promotion for him.

Once the lightning-rod known as health-care reform has it's fate decided, there are a lot of other things on the table where I think Brown will be extremely vulnerable. This is especially true in financial matters. Even on health-care reform, he was opposed to outlawing "anti pre-existing condition" legislation.

In his ads, he quite correctly talked about small business being an engine. If he doesn't watch out, he could get tagged with the Big Business Bush/Cheney TaxBreakForTheRich tag and that may be the death of him.

He cannot appear to be to overconfident - though, being in the minority party should help him maintain his 'underdog' image.
