Democrats flipped Virginia's state Senate and House of Delegates on Tuesday, while Kentucky Democrat Andy Beshear held a razor-thin lead over his Trump-backed opponent and the Republicans held on to win the Mississippi governor's mansion.

The big picture: Democrats' win in Virginia adds control of the House of Delegates and the state Senate to the governor's mansion. President Trump used the House impeachment inquiry against him as a political rallying cry in Mississippi and Kentucky gubernatorial races — but its success in campaigns has yet to be seen.

What you need to know

Virginia: Democrats now have the chance to push gun reform, expand Medicaid, raise the state's minimum wage and pass the Equal Rights Amendment, NPR reports. The past year's scandals involving Virginia's three top-ranking Democrats did not seem to keep voters from washing the state totally blue for the first time since 1992.

Mississippi: State Attorney General Jim Hood — an anti-abortion, pro-gun centrist Democrat — lost out to Republican Lt. Gov. Tate Reeves.

Kentucky: Democrat Andy Beshear held a narrow lead Tuesday night over Trump's pick for governor, incumbent Matt Bevin. A win from Beshear would suggest that the impeachment inquiry into Trump is not the useful 2020 strategy Republicans assumed it would be, even in Trump-friendly states.

Axios Re:Cap digs into the polls, and what pollsters have changed since 2016, with former FiveThirtyEight writer and current CNN politics analyst Harry Enten.

Twitter launches warnings on election misinformation and delays

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Why it matters: Delayed election results are expected across many states that are handling unprecedented amounts of absentee and mailed ballots, which President Trump has baselessly called "very dangerous" and "corrupt."

Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.
