LAS VEGAS (AP) — Joe Biden is declaring himself back into the race for the presidency after early results in Nevada showed the former vice president in second place.

Biden told supporters Saturday that “we’re alive and we’re coming back and we’re gonna win.” Biden thanked unions for their support, citing labor groups that have endorsed him including firefighters, ironworkers and electrical workers.

He took a shot at the race’s frontrunner, self-declared democratic socialist Bernie Sanders, and former New York Mayor Mike Bloomberg, who isn’t competing in the first four states but has spent hundreds of millions of dollars of his own fortune hoping to pick up delegates starting on Super Tuesday.

“I ain’t a socialist. I ain’t a plutocrat,” Biden said. “I’m a Democrat. And I’m proud of it.”

Biden said the Russians will continue to support President Donald Trump and Sanders, whose campaign acknowledged Friday that he was briefed last month by U.S. officials about Russian efforts to boost his candidacy.

“Let’s give Trump exactly what he doesn’t want,” Biden told his supporters. “Let’s give him you and Joe Biden as the nominee.”
