I guarantee that Mary McCarthy is a RAT. A lot of people wrongly assume that CIA and FBI personnel are conservatives. That all changed in the 90s under the Clintons when a lot of leftwing RATs got to work for those organizations. I also recall some woman in the CIA who was passing information along to Castro.
