If Democrats are going to minimize their losses this fall, the party has to mobilize enough of last cycle's so-called "Obama coalition" — largely young, minority and first-time voters in 2008. 

Those are all groups that are usually less likely to vote in midterm election years but will be key for Democrats in November.

The Democratic Congressional Campaign Committee is promising a robust get-out-the-vote effort this fall and is touting its start Monday with a Web video. 

It features Democratic field organizers talking up their efforts in scenes from the districts of several endangered Dems in 2010, including Reps. Mary Jo Kilroy (D-Ohio) and Tom Perriello (D-Va.). Watch it here

The committee has a series of house parties set for this week to drum up attention for Saturday's "National Day of Action." The goal is to knock on some 200,000 doors in what the committee says is the earliest it has ever started its GOTV efforts.

The DNC is also promising a $50 million effort in 2010, largely focused on field operations.
