The generic lead that Democrats are holding so far (10% among registered voters) is similar to 2004. Among likely voters, Democrats probably hold a 6-7% generic lead.
Yep. Help me out. Did the GOP lose 30 seats during '04? :-p
Again, generics are worthless in House and even Senate races. Redistricting means you can have one party ahead generically by 10 and still lose 20 seats.
