Democrats had a strong election night on Tuesday, leading the race for governor in Kentucky and taking back full control of the Virginia legislature for the first time in nearly a quarter century.

Voters in four states head to the polls on Tuesday for general statewide elections of note. These off-year contests may not be as high profile as the 2020 presidential and congressional elections will be a year from now, but they could offer some important hints on how voters are feeling about President Trump, impeachment, guns and more.

The ideological divisions between the leading Democratic candidates for president were on clear display at the rowdy Iowa Liberty and Justice Celebration on Friday evening.

Massachusetts Sen. Elizabeth Warren took aim at her more moderate rivals during her remarks, slamming them for "vague ideas that are designed not to offend anyone."

Former Texas Rep. Beto O'Rourke ended his presidential campaign on Friday after struggling to translate the energy from his 2018 Senate bid into a successful White House campaign.

"Our campaign has been about seeing clearly, speaking honestly and acting decisively in the best interests of America," O'Rourke wrote in a statement on Medium.

Ohio Rep. Tim Ryan has ended his struggling bid for the Democratic presidential nomination after failing to qualify for the past two primary debates.

Longtime U.S. diplomat William Taylor told lawmakers on Capitol Hill on Tuesday that President Trump orchestrated a parallel foreign policy for Ukraine that made U.S. aid to the country contingent on investigations to help himself politically.

In a written statement to three House committees tasked with Democrats' impeachment inquiry, Taylor said he "became increasingly concerned" as "irregular, informal channels" of policymaking diverged from official U.S. goals — led by Trump's personal attorney Rudy Giuliani.

President Trump is chastising Republicans for not sufficiently having his back as he tries to weather an impeachment inquiry from Democrats.

"Republicans have to get tougher and fight," Trump said during a Cabinet meeting on Monday. "We have some that are great fighters, but they have to get tougher and fight because the Democrats are trying to hurt the Republican Party for the election."

Rep. Alexandria Ocasio-Cortez of New York is set to endorse Sen. Bernie Sanders for president at a Saturday rally in Queens, N.Y., the campaign confirmed to NPR's Scott Detrow. It will be Sanders' first campaign event since he had a heart attack earlier this month.

Sanders teased the event during Tuesday's Democratic debate, saying there would be a "special guest" attending.
