If you are referring to Health Care Reform, I can't see how it would help elect Democrats. Americans oppose the bill by almost 2 to 1. Congressional approval levels are near all time lows. Fewer people identify themselves as Democrats than ever.
The way this bill was crafted, secret meetings, bribery, ignoring the people at Town Halls and at the marches has enraged and energized their opponents and dispirited their supporters.
They may have poisoned their chances for a generation.
