Current voting streak by each state in U.S. presidential elections 1964-2020

The Twenty-third Amendment to the U.S. Constitution granted citizens of the District of Columbia the right to vote in U.S. presidential elections; since this came into effect in 1964, the nation's capital has voted for the Democratic Party's nominee in every election, making this the longest ongoing streak in U.S. presidential elections. The record for the longest ever streak in the history of U.S. presidential elections belongs to Vermont (Republican) and Georgia (Democrat), who each voted for the same party's candidate in 27 consecutive elections between 1852 and 1960.

The south and west prove loyal

There are nine states, mostly across the West and Midwest, that have voted for the Republican candidate in all U.S. presidential elections since Richard Nixon's first victory in 1968. A number of other Republican streaks began in the south with Ronald Reagan's landslide victory in 1980, after briefly turning Democrat for Georgia's Jimmy Carter in 1976; historically the south had been a Democratic stronghold for more than a century, however the Republican Party's "Southern strategy" in the 1960s established them as the dominant party in the region during the civil rights era. Along with the District of Columbia, the only state not won by Reagan in 1984 was Minnesota, as Walter Mondale carried his home state by a very narrow margin. Minnesota's streak is the second-longest for the Democratic Party, while most of the other ongoing Democratic streaks began in either 1988 or 1992.

Recent swing states

In the 2016 election, there were six states (with 99 electoral votes combined) that had been won by Barack Obama in 2012, but turned red in 2016. In the 2020 election, Democratic nominee, Joe Biden, managed to win back three of these states, as well as ending a six election Republican streak in Georgia and a five election streak in Arizona. In contrast, Donald Trump failed to flip any further Democratic strongholds, but repeated his victories in Florida, Iowa and Ohio. Going into this election, pollsters had predicted that the races in both Texas and Florida would be tight, with a combined total of 67 electoral votes, however the incumbent president won the popular votes in these states with margins of roughly six and 3.5 percent respectively.
