In the 2000 election, how many districts for the US House did Gore and Bush each carry? Citation appreciated. Thanks!
This map doesn’t quite answer the question, but does show it visually:

The eighth table on this page does give the answer:

Gore won 209 congressional districts while Bush won 226. Of course, in many of these, the separation was probably even closer than in Florida.
