What are the party positions relative to OTL? I think it would be somewhat more left-wing in comparison to OTL due to a smaller military (because the US is not the only superpower ITTL).
Also, is the Republican Party still the party of the military (as it has been since the ACW IOTL) or have the Democrats replaced it as the main militaristic party?
I wouldn't say the parties are more left wing than OTL. Sure the military is smaller, but abortion is illegal in most states, English is the national language, and many places have prayer in school. There also isn't any Federally mandated Social Security/Medicare/Medicaid although certain states have versions of these programs.
Historically the military tends to lean Republican, however President Stewart's leadership in the recent war has led for a boost of military support for the Democrats.
Come to think of it, I am surprised that no one on this thread is calling for President Stewart to run for a third term.
