Sen. Kamala Harris of California blasts former Vice President Joe Biden for his previously held opinions on busing in schools. Debate night No. 2 marks the first time top-tier presidential candidates will confront one another in person over who is best fit to lead the Democratic effort to oust President Donald Trump in 2020. The sheer star power of the showdown Thursday at 9 p.m. Eastern amps up the pressure on candidates to stand out, pile on, fend off attacks or just survive. It's Joe Biden's night to show he commands the field. But it's Bernie Sanders' chance to show he's the one who understands today's Democratic Party. Pete Buttigieg could try to sound like a leader on the national stage, and Kamala Harris may aim to make a more personal impression. For all 10 candidates on stage in Miami, the forum is a chance to make Americans picture them as formidable foes to Trump over two hours of lightning-round questions. Here's what to watch on the second night of the first presidential debates, airing on NBC, MSNBC and Telemundo and steaming on this website: NBC 4 New York on Twitter: http://4.nbcny.com/kAuuwUN NBC 4 New York on Facebook: http://4.nbcny.com/mbeh714 NBC 4 New York on Instagram: http://4.nbcny.com/g5YlkcI NBC 4 New York on Youtube: http://4.nbcny.com/iTUpy5e #DemDebate #Politics #News
