For a reference point, '04 turnout was 37/37/26%
This is not 2004.
It's worth remembering that 2004 was the best presidential election of the last 24 years for the Republicans. So while Democrats may be a little oversampled here, it would be pretty silly to re-weight the sample so that Ds and Rs were at parity.
If I had to say, I'd say:
1) Republicans are more motivated than 2004
2) Romney is better with independents/moderates than Bush
3) Romney is a better candidate outside of the Bush states than Bush was.
#3 is still false. Romney is no better in the blue states (perhaps except Massachusetts and Michigan) than Bush was.
