A US map for Prez vote by Congressional District?

Hello, I’m a longtime reader who recently joined. I have a few questions for the minds here at SSP.

 

I was wondering if anyone has access to a map of the 2008 prez vote by CD.

If so, are there also maps for 2004 and 2000?

What about the 2000 stats on the Presidential Vote by CD? are they based upon the current district map, or the map used in 2000 (which is based on the 1990 census?)

Lastly, do we have precinct data for every CD?

Thanks so much.
