Voters in just a handful of states will effectively decide this November's presidential election. But which states flipped parties most recently and are seen as especially up for grabs?
Driving the news: The above maps show the last year each state went for a different party than it did in 2020, starting in 1964.
That's when Washington, D.C., residents were first able to vote in presidential contests (they went blue, for LBJ, and have voted that way ever since).
Zoom in: Minnesota — blue since '76 — is also as solid a Democratic stronghold as they come.
And a "red line" runs right through the middle of the country, with North Dakota, South Dakota, Nebraska, Kansas and Oklahoma going Republican since 1968.
Texas took a bit longer to start its streak; it's been red since 1980.
What's next: All eyes this year are on the states with the lightest shades of red and blue.
