Former President Donald Trump won South Dakota's three electoral votes for president Tuesday. The Republican nominee had been expected to prevail comfortably in a state where GOP voters outnumber Democrats by more than 2-to-1. No Democratic nominee has carried South Dakota since President Lyndon Johnson won in 1964. Trump received nearly 62% of the vote in each of his previous runs for president, and both times his margin was more than 26 percentage points. Almost 51% of the state's 616,000 registered voters are Republicans, while fewer than 24% are Democrats. The Associated Press declared Trump the winner at 9:00 p.m. EST.
