Riding a powerful "blue wave" of backlash to President Donald Trump, Democrats were projected on Tuesday night to take control of the House of Representatives in the midterm elections.

Tuesday night's results mark a comeback for the Democratic Party, which last held control of the House in 2010.

Democrats beat Republican incumbents with an energized and expanded voter base fueled by the anti-Trump resistance movement.

Democrats also ran the most diverse slate of candidates for the House in US history.

Riding a powerful "blue wave" of backlash to President Donald Trump, Democrats were projected to take control of the House of Representatives on Tuesday night in the midterm elections after eight years in the minority — a major blow to Trump's power in Washington.

Just after 10 p.m. ET, multiple media outlets projected that Democrats had flipped a dozen red seats in all corners of the country, including in Florida, New York, Pennsylvania, and Colorado.

"Today is more than about Democrats and Republicans," House minority leader Nancy Pelosi, now poised to become the majority leader, said during a victory speech on Tuesday night. "It's about restoring the Constitution and checks and balances to the Trump administration. It's about stopping the GOP and [Senate Majority Leader] Mitch McConnell's assault on Medicare, Medicaid, affordable health care, and millions of Americans living with pre-existing medical conditions."

Tuesday night's results mark a comeback for the Democratic Party, which last held control of the House in 2010, and will fundamentally shift the balance of power in Washington.

Flipping seats in every corner of the country, Democrats beat Republican incumbents with an energized and expanded voter base fueled by the anti-Trump resistance movement. A surge in millennial and black voters, coupled with a deep gender gap, helped propel Democrats to victory in dramatically different districts.

And Democrats ran the most diverse slate of candidates for the House in US history. Women and people of color made up nearly 60% of Democratic House candidates.

Enthusiasm for Tuesday's elections — exhibited in huge voter turnout — reached levels unprecedented in modern history with 28 states far exceeding (and some doubling) 2014 midterm turnout.

The future of the 'resistance' in the House

Democratic leadership has promised that they will move forward with investigations into the president's alleged wrongdoing while simultaneously pursuing possible bipartisan solutions on issues including infrastructure, gun safety, prescription drug prices, and a path to citizenship for DREAMers — undocumented immigrants who came to the US as children.

Democrats also say they'll focus on promoting stricter regulations on ethics and campaign finance — areas where Trump has been widely criticized.

Rep. Jim McGovern, the Massachusetts Democrat poised to chair the Rules Committee, said last month that House Democrats will seek to "restore some integrity" to Congress.

The party also plans to focus a significant amount of energy on reopening the House Intelligence Committee's now-shuttered investigation into Russian interference in the 2016 election and whether members of the Trump campaign colluded with Moscow to tilt the race in his favor.

Other Democratic policy priorities include improving the Affordable Care Act, better known as Obamacare, and addressing climate change.

Pelosi said in late October that Democrats would push to bring back a select committee on climate change — the Democrats' last such committee was shut down by Republicans when they took power in 2011.
