A former campaign advisor to Bill Clinton said that it's "plain as the sky is blue" that the economy does better under Democratic administrations than Republican ones.

"It's sort of like the Harry Potter school of economics, frankly," Rosenberg said, adding that the Trump budget's proposed cuts will in large part hurt Trump voters.

Rosenberg said that the last two Republican presidents have catalyzed recessions, lower incomes, and higher deficits, as opposed to the prosperity enjoyed under Democrats.

"Alright well we need all day to debate that," host Sandra Smith said.

"That's fact. That's fact. It's like the sky is blue," Rosenberg responded.

Budget Director Mick Mulvaney unveiled the new $4.1 trillion budget at the White House earlier today, saying it will measure compassion "by the number of people that we help," not the amount of funds spent.

Some of the cuts in the proposed Trump budget are $616 billion out of Medicaid, $193 billion out of food stamps, and $143 billion in student financial aid.

The federal government currently brings in $3.916 trillion in revenue and burns through it and more, spending $4.268 trillion.

Matt Schlapp, chairman of the American Conservative Union, pushed back on Rosenberg's assertion that the economy always does better under Democrats. 

"[If that were] a fact, then Hillary Clinton would be president," he said.
