WHERE GOP, DEMS WON

Democratic gains in the House came in densely populated, educated and diverse enclaves around the country, around major liberal cities like New York and Philadelphia and also red-state population centres like Houston and Oklahoma City. The Republican Party’s traditional base in these districts collapsed, with college-educated white voters joining with growing minority communities to support Democrats.

Republican victories in the Senate came mainly in the conservative strongholds where Trump’s popularity has remained steady or grown since 2016. With rural voters moving rightward and the Democratic Party moving left, Senate Democrats like Claire Mccaskill of Missouri and Joe Donnelly of Indiana found it impossible to reassemble the political coalitions that elected them in the past.
