Impeach Hillary Clinton? A boon for Democrats

President-elect Donald Trump delivers his acceptance speech in the early morning hours of Wednesday, November 9, as his running mate, Indiana Gov. Mike Pence, applauds in New York. The 2016 presidential campaign was one of the most dramatic and unpredictable races in U.S. history. How did we get to this point? Here's a look at how the campaign unfolded.

U.S. Sen. Ted Cruz, a conservative firebrand from Texas, stands on stage with his family March 25, 2015, after becoming the first Republican to announce a presidential run. Cruz, who made headlines with his staunch opposition to Obamacare and his willingness to shut down the federal government, presented a direct challenge to the expected bids of establishment Republicans such as Jeb Bush -- candidates Cruz coyly referred to as the "mushy middle."

Wisconsin Gov. Scott Walker is reflected by glass before speaking at a leadership summit in Nashua, New Hampshire, on April 18, 2015. Walker, who rose to national fame by taking on unions in one of the most blue-collar states, officially became a presidential candidate three months later.

U.S. Sen. Rand Paul, a Republican presidential candidate from Kentucky, looks down as New Hampshire Sen. Andy Sanborn, standing on a chair, makes opening remarks at the opening of Paul's campaign office in Manchester, New Hampshire, on June 5, 2015. Paul, the son of former U.S. Rep. Ron Paul, has carefully built a brand of mainstream libertarianism since riding the tea party wave into the Senate in 2010.

U.S. Sen. Lindsey Graham, a Republican from South Carolina, speaks to the media at a campaign stop in Waterloo, Iowa, on June 5, 2015. Graham, one of the Senate's leading foreign-policy hawks, announced earlier in the week that he would be running for President.

Democratic candidate Hillary Clinton, a former first lady and secretary of state, delivers a speech at a New York City park on June 13, 2015. Clinton used the first major rally of her campaign to make a populist case, declaring that the goal of her presidency would be to tip the nation's economic scales back toward the middle class' favor.

Democratic candidate Martin O'Malley, left, plays with a borrowed guitar during a meet-and-greet in Portsmouth, New Hampshire, on June 13, 2015.

Campaign volunteers with the Jeb Bush campaign inflate thunderstick noisemakers before he formally announced his candidacy in Miami on June 15, 2015. Bush, a scion of the most recognizable family in Republican politics, fashioned an image as a sober-minded conservative truth-teller while governor of Florida.

Donald Trump, a real estate mogul and TV reality star, announces himself as a Republican candidate during a news conference in New York on June 16, 2015. "Sadly the American dream is dead," Trump said at the end of his speech at the Trump Tower. "But if I get elected President I will bring it back bigger and better and stronger than ever before."

Supporters reach out to Trump as he leaves a stop in Laredo, Texas, on July 23, 2015. During a four-hour visit, Trump met with local officials and toured the border between the United States and Mexico. His visit was the culmination of more than a month of attention centered on Trump's branding of undocumented Mexican immigrants as killers and rapists -- remarks that drew condemnation from the Republican establishment but also helped rocket him to the top of the polls.

Trump raises his hand during the first Republican debates of the campaign, which took place in Cleveland on August 6, 2015. Trump kicked off the event by refusing to rule out a third-party run and pledge his support to whoever becomes the Republican nominee. He was joined on stage by nine other candidates -- seven of the lower-polling candidates had a separate debate before the main event.

Seconds after Sanders took the stage for a rally in Seattle, a dozen protesters from the city's Black Lives Matter chapter jumped barricades and grabbed the microphone on August 8, 2015. Holding a banner that said "Smash Racism," two of the protesters -- Marissa Johnson, left, and Mara Jacqueline Willaford -- addressed the crowd. Sanders stood just feet away off stage, chatting with his wife and the three aides that came to Seattle with him. His aides said the senator had no plans of leaving during the protests, but once Johnson did not appear willing to give up the mic after a moment of silence, organizers effectively shut down the event. Sanders never addressed the crowd, but he did make his way through it to shake hands and take pictures.

Keith Schiller, Trump's director of security and longtime bodyguard, holds back demonstrator Efrain Galicia at Trump Tower in New York on September 3, 2015. Galicia was among five protesters who later filed a lawsuit against Schiller, Trump, Trump's campaign and his company. The plaintiffs allege that Trump security officials, namely Schiller, assaulted them as they protested outside of a campaign event. A campaign spokesperson told The Washington Post that the protesters "were harassing people on the street" and that a Trump security guard was "jumped from behind."

Huckabee latched onto Davis as a symbol of the fight against what he said is government overreach.

Cruz and Trump joined forces in Washington during a tea party rally against the Iran nuclear deal on September 9, 2015. "It is a bit of a romance," Trump told CNN at the time. "I like him, he likes me. He's backed me 100% about illegal immigration. He was the one person that really -- and there were a couple of others -- but Ted Cruz was out there and he backed me very strongly."

Liberty University students pray before a Sanders speech in Lynchburg, Virginia, on September 14, 2015.

Trump, who had come under fire for his comments about Hispanics, seemed to understand how it might be perceived. "I swear to you -- I think she's totally beautiful and great -- I've never met her before, I swear," he said.

During a Democratic debate on October 13, 2015, Sanders and Clinton shared a lighthearted moment following Sanders' take on the Clinton email scandal.

Clinton said, "Thank you, me too," and then later shook his hand to the applause of the audience.
