Hillary Clinton Pledges to Never Let Donald Trump Become President Clinton is getting ready for the general election.

DETROIT, Michigan -- Hillary Clinton took direct aim at Donald Trump during a rally in Detroit tonight, vowing to never let the Republican front-runner become president as she continued to shift her focus away from Bernie Sanders and toward the GOP field.

“Because of the kind of campaign that the Republicans have been running, led by their front-runner, we have a lot of people who have been attacked, right?” Clinton asked the crowd of roughly 850 people at the Charles H. Wright Museum of African American History in Detroit.

The reference to Trump prompted loud “boos” from her supporters, which seemed to fire up Clinton. “I mean, you got to say this about him, he is an equal opportunity attacker,” she said about her possible future opponent in the general election. "He’s attacked Mexicans, he’s attacked people with disabilities, he’s attacked women, he has attacked Muslims. He’s just gone after everybody.”

She added: "We will not let a person like that ever become president of the United States."

Clinton made the remarks at her final rally ahead of Michigan primary tomorrow. Although her campaign is not yet ready to say the fight with Sanders is over, they are confident that come mid-March she will be too far ahead for her Democratic rival to catch up.

Tonight, Clinton was clearer than ever that she’s ready for the general election.

As she called on her supporters to vote for her, she added this plea: “The sooner I could become your nominee, the more I could begin to turn our attention to the Republicans.”

Sanders, meanwhile, won’t be dropping out anytime soon. "I think, geographically, we are looking good,” he said on Saturday. "I think we have a path toward victory.”
