NEW YORK (CBSNewYork)-- Hillary Clinton and Donald Trump are in a statistical dead heat.
One new national poll shows Clinton up three points in a general election match-up, CBS2's Brook Silva-Braga reported.
Another has Trump up two points. Both polls are within the margin of error. Last month Clinton enjoyed a double-digit lead.
"And that has tightened up principally because of the coalescing of the Republican Party and the failure to coalesce of the Democratic Party," Molly Ball of The Atlantic Magazine said.
Bernie Sanders continued his long shot Democratic bid with two rallies in California on Sunday. He polls better than Clinton against Trump, and argued that both have historically high unfavorable numbers.
"I don't want to see the American people voting for the lesser of two evils," Sanders said.
But Clinton is increasingly looking ahead to Trump, calling his proposals "dangerous."
"We're not going to let, at least my campaign is not going to let him normalize himself in this period," Clinton said.
One GOP group Trump has struggled to unite: big money donors. He told "Fox and Friends" that fully self-funding would require selling off assets.
"Now to finance a billion dollars, I would have to sell a building. I'd have to do something you know, like that. Will I do that? I could," he said.
Polling also shows that roughly half of Clinton and Trump supporters will vote for one because they so strongly dislike the other.
