We'll just mark it down as a gaffe on your part.
Not so fast there my.........oh, wait. Nevermind. In any case, the definition of posse refers to a "group" of people. We have 3 Trump Groupies(when Howard decides to leave Mom's basement for a bit), 1 Feel the Bern guy, Uncle Joe is sitting all alone on(or off) his rocker on the porch of the Shady Rest, 1 guy who hates everybody, and the rest of us are just sitting here enjoying our popcorn waiting for the 'real' circus to start. So I'd say the only group that qualifies as a "posse" would be the Trump Groupies. Or in this case, should it be spelled Trump's Pusse?
