WSJ's James Taranto frequently (and cleverly) referred to our retiring, party-switching senior senator this way: Arlen Specter (R2D2 Pa.)

Apparently, he has a new phone coming out:

Star Wars-themed R2-D2 smartphone with Binoculars app to launch

p.s. Would that would that make Sen. Bob Casey C3P-O? Because we can see a resemblence.
