Republicans and even some Democrats swooned when Rep. Alexandria Ocasio-Cortez pitched a 70 percent tax rate on the rich — but a new poll out Tuesday showed that most Americans like the idea.

The Hill-HarrisX survey found that 59 percent of US voters support raising the top rate to 70 percent, which she said would be applied to income above the first $10 million taxpayers earn.

Women back the idea by a 62 percent to 38 percent margin, while men support it by 55 percent to 45 percent.

According to the poll, 45 percent of Republican voters said they favored it while 55 percent were opposed.

Independent voters backed the plan by a 60 to 40 percent margin while Democrats supported it, 71 percent to 29 percent.

Ocasio-Cortez reacted to the survey on Twitter — taking a shot at her critics as well.

“Oh? What’s that? The majority of Americans respect when you break down reasonable policy proposals that are designed to combat runaway income inequality and help fund priorities they value most?” she wrote. “We can win public sentiment, stand our ground, & not be scared by GOP information.”

In an appearance on “60 Minutes,” Ocasio-Cortez talked about the tax rates that were in place in the 1950s and ’60s, when the wealthiest Americans were taxed at a rate of more than 90 percent.

“That doesn’t mean all $10 million are taxed at an extremely high rate, but it means that as you climb up this ladder you should be contributing more,” she said.

Republicans charged that she wanted to tax all income at that rate, not just that earned after the first $10 million.
