I'm trying to find the results for the amount of votes for the Democratic party per congressional district and all I can find is the amount of votes per county, and since some congressional districts go through half a county, it isn't very helpful. I was wondering if anyone knew a great website that broke down the election results by congressional districts rather than by county.
Daily Kos published the presidential results by congressional district for the 2012 and 2016 elections. It is quite comprehensive and includes their detailed calculations.
There is also an analysis done by The Cook Political Report which is accessible here.
