WASHINGTON/PHOENIX, Arizona/BIRMINGHAM, Michigan – Senate incumbents including Democratic leader Chuck Schumer and senior Republican John Thune won re-election in Tuesday's US midterm elections, on a day Republicans were expected to wrest control of Congress away from President Joe Biden's Democrats.

Three dozen governors' races are at stake as well; Florida Governor Ron DeSantis, a possible contender for the Republican presidential nomination in 2024, defeated Democratic Representative Charlie Crist, Edison Research projected

Thirty-five Senate seats and all 435 House of Representatives seats are on the ballot. Republicans are widely favored to pick up the five seats they need to take over the House, but control of the Senate could come down to tight races in Pennsylvania, Nevada, Georgia and Arizona.

Three dozen governors' races are at stake as well; Florida Governor Ron DeSantis, a possible contender for the Republican presidential nomination in 2024, defeated Democratic Representative Charlie Crist, Edison Research projected.

The final outcome, particularly control of the 50-50 Senate, is unlikely to be known any time soon. Democrats currently control that chamber through Vice-President Kamala Harris' tie-breaking vote.

In swing states such as Nevada, Arizona and Michigan, the Republican nominees to head up the states' election apparatus have embraced former president Donald Trump's falsehoods, raising fears among Democrats that, if they prevail, they could interfere with the 2024 presidential race

The problems stoked evidence-free claims among former president Donald Trump and his supporters that the failures were deliberate.

Scores of Republican candidates have echoed Trump's false claims that his 2020 loss to Biden was due to widespread fraud.

Economic worries

The party that occupies the White House almost always loses seats in midterm elections, but Democrats had hoped the Supreme Court's June decision to overturn the nationwide right to abortion would help them defy that history.

President Joe Biden was expected to watch the results from the White House, where the usually quiet corridors were abuzz with aides. A Biden adviser, anticipating a tough evening, said Democrats had done the best they could given higher gas prices and inflation

But stubbornly high inflation, which at 8.2 percent stands at the highest rate in 40 years, has weighed on their chances throughout the campaign.

"The economy is terrible. I blame the current administration for that," said Bethany Hadelman, who said she voted for Republican candidates in Alpharetta, Georgia.

Fears of rising crime were also a factor in left-leaning areas like New York, where incumbent Democratic Governor Kathy Hochul faced a tough challenge from Republican Lee Zeldin.

"We have criminals constantly repeating crimes. They go to jail and come out a few hours later or the next day," said John Delsanto, 35, a legal assistant in New York City who said he voted for Zeldin.

A Reuters/Ipsos poll this week found just 39 percent of Americans approved of the way Biden has done his job. Some Democratic candidates deliberately distanced themselves from the White House as Biden's popularity languished.

Trump's polling is similarly low, with just 41 percent of respondents to a separate recent Reuters/Ipsos poll saying they viewed him favorably.

In Congress, a Republican-controlled House would be able to block bills addressing Democratic priorities such as abortion rights and climate change, while a Republican Senate would hold sway over Biden's judicial nominations, including any Supreme Court vacancy.
