In a speech to a crowd that his campaign estimated at thousands, the retired neurosurgeon and unlikely conservative star introduced his wife and family and called for "the people to rise up and take the government back." Carson told the story of his rise from poverty, where he lived in homes infested with roaches — "in the more upscale areas, they called 'em waterbugs, but we knew what they were" he joked — and promised that he wouldn't change his signature style, framing himself as an outsider up against the political elite.
"I'm probably never going to be politically correct because I'm not a politician," he said. "I don't want to be a politician. Because politicians do what is politically expedient — I want to do what's right."
Carson's theatrical announcement event included a gospel choir singing a medley topped by Eminem's "Lose Yourself," but the celebratory tone of the day was shrouded in private sadness for the candidate. His campaign confirmed earlier Monday that Carson's ailing mother was growing progressively sicker, and he planned to delay his planned trip to Iowa to head to Dallas on Monday to say goodbye.
But the notoriously sharp-tongued orator maintained his calm demeanor on stage Monday, taking sharp jabs at everything from the media to the Obama administration's policies. He called for an end to social programs that "create dependency," and, signaling he may seek to play in Capitol Hill battles, telling supporters that if their lawmaker voted to raise the debt limit, "you need to throw them out of office."
Carson demanded another "wave election" this cycle, not of Republicans (who already control both chambers of Congress), but rather to elect "people with common sense who actually love our nation, and are willing to work for our nation, and are more concerned about the next generation than the next election."
And he also weighed in on the recent unrest in Baltimore, following the death of an African American man in police custody, declaring that the "real issue is that people are losing hope" because the economy isn't delivering for them.
"They don't feel that life is going to be good for them, no matter what happens, so when an opportunity comes to loot, to riot, to get mine, they take it, not believing that there is a much better way to get the things that they desire," Carson said.
Carson is so far the only African-American presidential candidate from either party. He cuts an unusual figure for the GOP, but that's part of his appeal for conservatives.
He made his name in medicine by becoming the first surgeon to successfully separate conjoined twins at the head, and was played by Cuba Gooding, Jr. in a TNT adaptation of his memoir.
Carson grew up poor in Detroit and went on to get degrees from Yale and the University of Michigan, ultimately going on to become the director of pediatric neurosurgery at Johns Hopkins by the age of 33. He's written six best-selling books, is a regular on the paid speaking circuit and was ranked the sixth most admired man in the world in a 2014 Gallup poll.
And he has been brazenly critical of President Barack Obama's policies — often to the point of getting himself in trouble with his borderline incendiary comments, including times he's compared Obamacare to slavery and the U.S. to Nazi Germany.
That unapologetic bluntness has made Carson a conservative star. He typically polls in the middle of the GOP presidential pack, ahead of second-timers like Rick Santorum and Rick Perry, and came in fourth at this year's Conservative Political Action Conference.
But it's also the thing that could halt his rise in its tracks. He faces strong skepticism from the GOP establishment over his penchant for controversial comments, which many Republicans worry could create headaches for the whole party and jeopardize their chances in the general election.
He told WKRC, however, that he's learned his lesson from those controversies.
"I don't wander off into those extraneous areas that can be exploited. I have learned that," he said.
"Moral decay and fiscal irresponsibility"
Two years ago, however, it was Carson's signature brashness that brought him to national prominence and launched his rise as a conservative star.
Standing just feet from the president at the 2013 National Prayer Breakfast, Carson knocked Obama's policies, lamented the nation's decline and warned of the "moral decay and fiscal irresponsibility" confronting America.
The comments drew widespread plaudits from conservative commentators and, according to Carson, the ire of the White House. He refused to back down, and has struck a similarly aggressive tone in criticizing everything from gay marriage — which he's likened to beastiality — to Obamacare, which he's called "the worst thing that has happened in this nation since slavery."
Carson did, however, recently apologize after telling CNN that being gay is a choice because people "go into prison straight — and when they come out, they're gay." In a subsequent Facebook post, Carson said that "my choice of language does not reflect fully my heart on gay issues."
"I do not pretend to know how every individual came to their sexual orientation. I regret that my words to express that concept were hurtful and divisive," Carson wrote.
But he rarely walks such comments back because, he says, he has no use for the "PC Police."
While critics may see Carson as unpolished, he and his advisers believe his plainspoken style contributes to his appeal as a political outsider up against a spate of Washington and Republican Party insiders.
That crusade against political correctness and the Washington establishment has helped him amass a strong grassroots conservative following that his advisers believe will help him lock down the funds he'll need to compete.
His campaign reportedly plans to raise $65 million between now and the Florida GOP primary, and another $65 million after that. Carson's presidential exploratory committee ended March with nearly $1.7 million cash on hand, after raising over $2.1 million in the first three months of the year.
But with his more prominent primary opponents planning to raise upwards of $100 million for their campaigns, Carson may struggle to break through the noise of an increasingly crowded Republican presidential primary.
