Following Super Tuesday wins, Hillary Clinton holds rally in New York City

MIDTOWN, New York City (WABC) -- Hillary Clinton was in New York City Wednesday for a series of events after her Super Tuesday victories.

The Democratic presidential candidate spoke to supporters at the Jacob K. Javits Convention Center on the West Side in Midtown.

"Wow! It is so good to be home!" said Hillary Clinton, (D) Presidential Candidate.

She was back in the state she represented for eight years, back among a coalition of allies from organized labor. Hillary Clinton stood in the Javits Center Wednesday night, ignoring her primary opponent. She focused instead on the rhetoric of Republican Donald Trump without once saying his name.

"I'll tell you this is serious business. It really matters when you're running for president what you say. And boy does it really matter when you are the president about what you say and how the rest of the world hears you," Clinton said.

The Republican front-runner was uncharacteristically silent Wednesday with a day away from the cameras after sweeping through seven Super Tuesday states.

And Wednesday night, the list of Republican candidates who are not named Donald Trump is one name shorter.

Dr. Ben Carson is signaling that he may be out of the race by the end of the week.

"Please everyone get together so we can keep this front-runner from winning and destroying the Republican Party!" said Sen. Marco Rubio, (R) Presidential Candidate.

Florida Senator Rubio cast his early ballot for his state's primary, seen as a must win for him on March 15th, the same date Ohio Governor John Kasich will have the same imperative for his home state primary.

Tuesday night, Texas Senator Ted Cruz held his own state, meaning with the three of them still in the race they're effectively splitting the anti-Trump vote.

Thursday, Mitt Romney plans to lay out a case against Trump as the party plants to blast away at him with negative ads.

Meanwhile, Vermont Senator Bernie Sanders is defiantly staying in the Democratic race, despite losing Massachusetts, which his campaign had promised to win.

"We were up against somebody who had been anointed as the inevitable nominee. Well guess what? She's not so inevitable today," Sen. Sanders said.

Tell that to her supporters back at the Javits Center.

"I love Bernie, but this woman can get things done," a Clinton supporter said.

"She's the best! She's the best, number one!" another supporter said.

Later Wednesday evening, she joined former President Bill Clinton and her daughter, Chelsea Clinton, for the "I'm With Her" fundraising concert, featuring Katy Perry and Elton John at Radio City Music Hall. All three Clintons delivered speeches.

On Super Tuesday, Clinton collected wins in seven states: Alabama, Arkansas, Georgia, Massachusetts, Tennessee, Texas and Virginia, as well as American Samoa. She is assured of winning at least 457 of the 865 delegates at stake Tuesday. Her opponent Vermont Sen. Bernie Sanders will gain at least 286. When including party leaders, Clinton has at least 1,005 delegates and Sanders has at least 373.

Clinton strongly prevailed among Hispanics and African-Americans, according to exit polls conducted for The Associated Press and television networks by Edison Research.
