Next Liberals could have a voter registration drive for Al Qaeda, Hamas, ISIS, Boca Haram, the Iranian Mullahs, people living in Cuba, Venezuela, Syria and anywhere else enemies of the USA hang out? Then again, Liberals may have a hard time controlling that base just as they fail to control the wackos they have in their base now.
I was thinking of the "Sister Cities" relationships so many American cities have with cities in foreign countries.
The next step could well be a push to extend American voting rights to residents if "Sister Cites" around the world.
Philadelphia (for example) has the following "Sister Cities":
Florence, Italy
Tel Aviv
Torun, Poland
Tianjin, China
Nizhny Novgorod, Russia
