Democratic Party House Minority Leader, Nancy Pelosi. She has been suggested as the next Speaker of the US House of Representatives.

Democrats have picked up previously held Republican seats to take the majority in the House of Representative while the Senate Republicans expanded their majority in a keenly contested mid-term election.

The results create a divided Capitol Hill next year and mean President Trump’s plans for new tax cuts, tougher immigration legislation and changes to the Affordable Care Act may be blocked.

House Minority Leader Nancy Pelosi, D-Calif., declared victory late Tuesday night and Trump called her to congratulate her on the win.

“We have all had enough of division. The American people want peace; they want results; they want us to work for positive results for their lives,” Pelosi said at an election night celebration.

Senate Democrats in several red states suffered projected losses after Trump’s concentrated focus on rallying in the final weeks of the campaign.

Republicans will maintain control of the Senate for at least two more years, after Democratic losses in Indiana, Tennessee, Texas and North Dakota – states that Trump won by double digits in 2016. The president campaigned aggressively in those states.

Senate GOP leaders capitalized on a battleground map that left Democrats defending 26 seats, including 10 in states Trump won in 2016.

Alhough Donald trump was not on the ballot. the midterm election was viewed as a nationwide referendum on his leadership. Democrats in the House vow to launch wide-ranging investigations into Trump, his business dealings and the transparency of his administration. Republicans in the Senate will continue to install more Trump nominees in the federal judiciary and defend the president and his policies.

Pelosi’s spokesman, Drew Hammill, tweeted late Tuesday about the phone call between the president and the House minority leader: “President Trump called Leader Pelosi at 11:45 p.m. this evening to extend his congratulations on winning a Democratic House majority. He acknowledged the Leader’s call for bipartisanship in her victory remarks.”

A divided Congress is likely to extend the heated battles of the 2018 campaign into the presidential election in 2020.
