I know she's eccentric and flambuoyant in some ways, but she's pretty smart. I doubt she's a lefty.
She’s hard to characterize. You are right, she’s not really a classic leftist, but here is an interesting paragraph from Wikipedia:
“Some of her views have been characterized as conservative, but Paglia characterizes herself as a Clinton Democrat and libertarian. She opposes laws against prostitution, pornography, drugs, and abortion. Paglia criticized Clinton for not resigning after the Monica Lewinsky scandal, which she says led to America being “blindsided by 9/11”. In the 2000 US presidential campaign she voted for the Green Party candidate Ralph Nader, “[because] I detest the arrogant, corrupt superstructure of the Democratic Party, with which I remain stubbornly registered”. In the 2004 U.S. presidential election, Paglia supported John Kerry; and in 2008, she supported Barack Obama.”
