OMAHA, Neb. (AP) — Nebraska will never be mistaken for a swing state given that it hasn’t supported a Democratic presidential candidate since 1964, but if the race is close this fall, the state could have a key role in choosing the next president.

It’s all thanks to a law approved decades ago that was intended to attract presidential candidates to a state they usually ignore because it’s so reliably conservative. While the statewide vote will clearly go to President Donald Trump, former Vice President Joe Biden has a good chance of winning in the state’s 2nd Congressional District, meaning one of Nebraska’s five Electoral College votes could go to the Democrat.

But there’s a problem with that scenario: Maine.

Maine is the only other state that awards Electoral College votes by congressional district, and it could go the opposite way and award a vote to Donald Trump even as the state as a whole likely will go to Biden.
