Who to credit for the Democratic sweep?

Somehow, the astonishing and amazing idea has spread that the recent election was a victory for conservative Democrats. Hardly! Rahm Emanuel represents the DLC, the group that oversaw the disastrous losses of 1994 (New Gingrich called it the "Republican Revolution.") and that failed to get the Democratic majority back (Except for a few razor-thin Senate wins) for the rest of the years of their grip on Democratic strategy. Emanuel is hardly any sort of genius strategist, in fact, the blogger Digby quotes the New Republic to show that, while not all of Emaneul's candidates failed, Emanuel was very clearly NOT the crucial factor tha made the difference. This was not the year of the conservative, corporatized DLC. 2006 was the year of the grassroots, the year of the bloggers, the years of "the fighting progressives."
In fact, DailyKos is complaining about the "...most moronic media lines last night, and continuing through today, [that] is how 'conservative' these newly elected Democrats are." After listing numerous successful House and Senate candidates who can't possibly described as conservative, he ends up concluding: "...during the campaign, every single one of these Democrats was accused by their Republican opponents of being 'too liberal'. Every single one of them."
