The Labour party has won over 400+ seats (out of 650) in the 2024 UK General Elections, and Keir Starmer is expected to replace Rishi Sunak as Prime Minister. The Conservatives, in power for the last fourteen years, have suffered a rout, losing over two-thirds of their seats. The SNP has collapsed in Scotland, mostly to Labour, and the Liberal Democrats have gained over sixty seats.
Which would make the best chance to keep Trump out would be a third candidate that was a “moderate” republican. Somebody that took the more centrist base away from him.
