MA are Republicans, NA are Democrats, you can debate that, but not really. I don't believe this was unintentional.
Financially advanced (Iron-man, Wonder-man, Wasp) or Militarily leaning characters ( Ms Marvel, Black Widow, Ares) and weak-minded (Yellowjacket, Sentry)(this may raise some hackles) not to mention most powerful- Republican
Weaker group, looking out for the most vulnerable of citizens (Cap, Spiderman, Wolverine, Cage, Doc Strange, Hawkeye, Iron Fist, Echo, or Daredevil) underdogs all. Not sure about Spiderwoman.-Democrat

Corporate vs. man on the street.

Republicans won the Civil War battle. Dems will win the final battle and ultimately the war-shortly before the '08 elections.

Is this orchestrated?
