Donnelly's presidency seems to have defeated the purpose of having a Socialist Party.
^this, though I wouldn't mind a Socialist Party. A breakaway right-wing party (supporting a complete return to the gold standard, repealing the 16th Amendment and all Federal labor regulations, etc) would also be interesting.
Has the equivalent of the 17th Amendment been passed in this timeline? If not, the PA is in for a landslide congressional defeat, which will probably happen regardless, but will be especially bad if Senators are still chosen by State legislatures.
Anyway, as much as it pains me, I must vote McKinley.
