Splitters!

The Unionists parties and candidates are arguing over who is splitting the Unionist vote. The DUP has rounded on the UKUP and assorted independents. The UUP blames the DUP for starting it all while independents have pretty much told the DUP to get stuffed. So who exactly is the PFJ, the JPF (Suicide squad) and the JPPF in all this?

The relevant scene:
REG:
Right. You’re in. Listen. The only people we hate more than the Romans are the fucking Judean People’s Front.
P.F.J.:
Yeah…
JUDITH:
Splitters.
P.F.J.:
Splitters…
FRANCIS:
And the Judean Popular People’s Front.
P.F.J.:
Yeah. Oh, yeah. Splitters. Splitters…
LORETTA:
And the People’s Front of Judea.
P.F.J.:
Yeah. Splitters. Splitters…
REG:
What?
LORETTA:
The People’s Front of Judea. Splitters.
REG:
We’re the People’s Front of Judea!
LORETTA:
Oh. I thought we were the Popular Front.
REG:
People’s Front! C-huh.
FRANCIS:
Whatever happened to the Popular Front, Reg?
REG:
He’s over there.
P.F.J.:
Splitter!
