Former longtime CNBC correspondent and anchor Michelle Caruso-Cabrera has launched a challenge in the Democratic primary against freshman firebrand Rep. Alexandria Ocasio-Cortez (D-NY), CNBC reports.

“Caruso-Cabrera is known to be a skeptic of government and a proponent of free markets. In 2010, she published a book called You Know I’m Right: More Prosperity, Less Government. She has been a registered Democrat for several years.”

A new Siena poll finds Rep. Alexandria Ocasio-Cortez (D-NY) has a positive 52% to 33% favorability rating among voters of her district nearly three months into her first term in Congress.

This is the moment Alexandria Ocasio-Cortez (D), a 28-year-old running her first campaign, discovered she had ousted veteran Rep. Joe Crowley (D-NY) in New York’s 14th congressional district.
