Early results from the United States midterm elections show Democrats leading in several seats previously held by Republicans, raising concerns that President Donald Trump's party could lose control of Congress.

If Democrats secure a majority in the House of Representatives, they would be positioned to block Trump's legislative agenda and launch investigations into his administration.

According to the media outlet NDTV, vote counting is underway in several states, including Ohio, Georgia, and North Carolina.

This election will determine the balance of power in Congress for the remaining two years of President Donald Trump's term in the White House.

Early returns indicate that Democrats are leading in several Republican-held seats, which could deliver a major blow to Trump's grip on Washington and limit his power for the remainder of his presidency.

Data from the BBC shows that out of 35 seats contested in the 100-member Senate, results for 9 seats have been declared.

Overall, Democrats hold 43 seats and Republicans hold 31.

In the House of Representatives, results for 52 seats have come in so far, with Democrats winning 36 seats and Republicans 16. A total of 218 seats are required for a majority in the House.

Meanwhile, according to Al Jazeera, Democrats have won 43 seats in the House so far compared to 19 for the Republicans, while leading in 99 and 69 seats respectively, with the outcome of 205 seats still pending.

In the Senate, Democrats have secured 43 seats and Republicans 32, with Democrats leading in 7 more seats and Republicans in 6.

The results for 12 Senate seats are yet to come. A majority in the Senate requires 51 seats.

Early projections and trends have sparked anxiety among several Republican (GOP) leaders involved in the House races, who fear the outcome may favor the Democrats.

A Republican official in Georgia told CNN that several GOP campaign teams are worried about voter turnout across the state, expressing doubt over whether they can secure enough votes to guarantee victory against Democrats as the outcomes of key Senate and gubernatorial races remain uncertain.

If Republicans lose their majority in the House, Democrats would gain the power to stall Trump’s legislative plans.

Furthermore, they could launch widespread investigations into his administration.

Defeat in the Senate as well would threaten Trump's authority to appoint Supreme Court justices and senior officials.

Amid a rising cost of living and the war against Iran, public opinion against Republicans has rapidly soured. Consequently, the election results are also being viewed nationwide as a referendum on Trump’s presidency.

This year's midterm elections are contesting all 435 seats in the House of Representatives, 35 seats in the 100-member Senate, and gubernatorial races in 36 states.

Democrats need a net gain of just three seats to reclaim a majority in the House, and four seats to capture a majority in the Senate, which could strip Republicans of control over both chambers.

However, winning a Senate majority remains a steep challenge for Democrats. Republicans currently hold a 53–47 majority in the Senate.

Nevertheless, public discontent has expanded political competition even into traditionally reliable, conservative-leaning states such as Kansas, Texas, Iowa, Ohio, and Alaska.

On the other hand, Democrats also face challenges holding onto competitive seats, such as in Michigan.

In Michigan, internal party bitterness led Congresswoman Haley Stevens to endorse Republican Mike Rogers over Democratic candidate Abdul El-Sayed.

A final forecast by Decision Desk HQ projects that Democrats could win 241 seats in the House and Republicans 194. In the Senate, the Democratic majority is projected to be narrower, at 52–48.
