The previously Democratic governorship of Missouri passed into Republican hands, with Democratic State Atty. Gen. Chris Koster losing out to Eric Greitens, a onetime Navy SEAL who served in Iraq and Afghanistan.
The wealthiest Californians will continue to pay higher income taxes as voters look to have approved Proposition 55.
In returns as of late Tuesday night, the measure led with more than 61% of votes counted.
"California voters have once again stood up for our children and schools in approving Proposition 55 to protect critical funding for education and keep vital services intact," Jennifer Wonnacott, spokeswoman for Yes on 55, said in a statement.
Pennsylvania Sen. Pat Toomey successfully beat back a challenge by Democrat Katie McGinty to claim his second term.
The Republican had fought for most of the general election against a strong Democratic headwind in the state, as many of the moderate voters who determine Pennsylvania elections sided with Hillary Clinton and McGinty.
Seeking not to further alienate them, Toomey throughout the race declined to say whether he would vote for his fellow Republican Donald Trump, instead lamenting the choice facing voters in the presidential race.
How did the newly weakened Voting Rights Act impact election results?
In short, it's very hard to know yet.
Tuesday election was the first since a monumental Supreme Court ruling in 2013 struck down key part of Voting Rights Act, leading to sweeping changes in voting rules across a swath of Southern states and several other districts or states that had historically discriminated against minorities.
Californians have chosen to make permanent the hospital fee program that helps fund Medi-Cal, the state's subsidized healthcare program for low-income residents.
Early election returns show the measure passing with more than 70% of the vote. Proposition 52 willhobble state lawmakers' ability to change or end the hospital fee program.
Through the program, hospitals pay to generate a federal contribution to Medi-Cal that results in a net benefit to the hospitals. During the fiscal year that ended in June 2016, the program generated $4.4 billion in federal funding for Medi-Cal.
In light of Tuesday’s election returns, the poll now looks like the only major survey to see the wave coming.
Most of the summer and fall, the poll's results have been about 6 percentage points more favorable to the Republican than the polling averages. As of Tuesday morning, the poll's final forecast for the election showed Trump leading by a little over 3 points, 46.8% to 43.6%.
An ambitious measure to raise the Los Angeles County sales tax and dramatically expand the mass transit system took an early lead Tuesday night in early and absentee voting, just passing the two-thirds threshold needed for victory with 9% of precincts reporting.
The early tally showed 67.28% of voters favored the half-cent sales tax increase. That's above the 66.67% threshold it needs to win.
"I'm superstitious. I don't ever declare victory until the end," said Los Angeles Mayor Eric Garcetti. But, he added, early results looked "very promising."
Hillary Clinton had been leading all along. Or that's what the polls said for months, and thus what the poll-tracking sites said for months. That's part of the story of tonight: the mood of mild certainty that had rippled through Clinton supporters' friend circles and their Facebook feeds. It had given Democrats the deceptive feeling of a tailwind as they glided out of the final years of the Obama administration. That's all gone now.
