A paid political campaign operative, working particularly for liberty-oriented Republican candidates. Bentonites have porous principles (if they have any principles at all) and are formed by anti-social psychopathic behavior and the decomposition of the US Constitution. Bentonites have heads that swell 5 to 6 times their original volume in the presence of large amounts of grassroots donations. Bentonites are most useful in sucking up to establishment Republicans, sabotaging political campaigns, paying themselves outrageous salaries, and betraying liberty.
The word became popularized during the 2012 Ron Paul Presidential Campaign.
"What happened to our national delegate majorities in all those states?"
"Yeah, unfortunately they were outed and de-credentialed with the help of a bentonite."
