Bill de Blasio, the liberal Democratic mayor of New York, is emerging as a popular punching bag for Republicans.

The latest to take a few swings is Louisiana Gov. Bobby Jindal (R), who in an op-ed for the New York Post labels de Blasio's education policies a "war for poverty."

Jindal focuses in particular on de Blasio's push to cut funding for charter schools and not allow them to operate out of public school facilities. The mayor has clashed in particular with the founder of one charter network, Eva Moskowitz.

"The mayor’s open warfare against Eva Moskowitz, who founded a network of 22 charter schools, has all the markings of a petulant tyrant holding low-income students hostage," Jindal said. "De Blasio has said, 'There’s no way in hell Eva Moskowitz should get free rent' — as if the 6,700 students in the charter schools she runs were a mere afterthought in his personal vendetta against a fellow Democrat."

Jindal, a potential 2016 GOP presidential candidate, has focused intently on the issues of vouchers and charter schools. In his speech at the Conservative Political Action Conference earlier this month, he compared Attorney General Eric Holder to segregationist former Alabama governor George Wallace (D) and Wallace's "Stand in the Schoolhouse Door" to stop integration of the University of Alabama.

The Justice Department later pointed out that one of the two students Wallace attempted to thwart was, in fact, Holder's late sister-in-law.
