If you'll get rid of the Kennedys, we'll take care of the rest.
At the risk of starting a flame war with formerlurker, I dare say that a great many of the miscreants we get on this side of the border originally hail from the DPRM (Demokratik People's Republik of Massholeistan). A sampling:
Michael Addison--murdered Manchester officer Michael Briggs--Masshole
Leland Eisenberg--took hostages at Clinton campaign office in Rochester--originally Masshole
Melein Meas--wanted for murder, arrested in NH--Masshole
I could go on and on and on, but you get the idea.
