Surprise! Nancy Pelosi's powder pal doesn't just think Katherine Harris is a "remarkable lady"—as we reported after perusing what appear to be his Free Republic posts—he puts his money where his mouth is.

According to an FBI affidavit obtained by Radar, Chad Conrad Castagana, who was arrested Monday on suspicion of sending powder-filled envelopes to Keith Olbermann, Jon Stewart, Sumner Redstone, David Letterman, Pelosi, and New York Senator Charles Schumer, purchased a $15 money order made out to "Friends of Katherine Harris" last September at a Woodland Hills, Calif., post office while he was picking up the envelopes and stamps he employed to terrorize the liberal elite.

According to the affidavit, Castagana, an "average looking" 39-year-old white guy who lives with his parents in Woodland Hills, attempted to send 13 fake anthrax letters to the aforementioned victims starting in September. We say "attempted" because the first letter, which contained the message, "Do you know Alan Berg? You should. Death to demagogues," and a harmless white powder, was sent to a poor sap on the Upper West Side named Jon Stewart—but not that Jon Stewart. (Alan Berg is the Jewish talk-radio host murdered by white-supremacists in Denver in 1984.)

Not to worry—according to the affidavit, Castagana sent back-up letters to Stewart's office at Comedy Central and his actual home address. All bore return addresses from left-leaning luminaries like Norman Lear, Susan Estrich and ... William Shatner.

One of the Stewart letters featured a "picture of a recently deceased tsunami victim with a condition known as Priapism, an erect penis on a cadaver." Handwritten on the picture were the words, "Jon Stewart, Fuck Your Wife."

Stay Classy, Katherine Harris supporters!

Here are some of Castagana's other white-powder MASH notes:

To Olbermann: "There are too many demagogues in America. All of you are poisoning the well! Time to give your kind a taste of your own medicine."

To Redstone: "Fuck You Mr Monopolist [sic]"

To Letterman: "more then one way to frag a demagogue... your kind are the real poison [sic]"

To Pelosi: "CUNTFACE. IMPEACH THIS."

None of the letters contained biohazardous substances. According to the affidavit, the feds tracked Castagana down by tracing the purchases of the Ready Post envelopes he used to mail the letters, two of which were purchased at a Woodland Hills post office on the same day letters to Stewart and Olbermann were postmarked.

Calls to the campaign office of Harris, who lost her bid for Senate last week, went unreturned.
