How to read it. A state's presidential vote is its result in the latest presidential election on or before the Senate race. Colour is the winner's party; a winner recorded without a major party (purple) is not counted as a crossover, and that includes Alaska's 2010 write-in winner, whom the record holds as an independent. Rows hold the races of each even year, not the whole chamber: a senator elected in an earlier year shows in that year's row. Alabama's December 2017 special is left out.
