You guys are ridiculous. You're making such a fuss about one or two people voting tactically.
It changed the results of at least two elections
No it didn't.
At the very least, it changed the results of the 1916 Republican Primary, which by extension, changed the result of the general.
Don't be silly, Debs would have won anyway. Did you see his margin of victory?
Debs would have won anyway in 1920, sure, but I am referring to 1916, Roosevelt's victory in WWI. Roosevelt was nominated because of tactical voting by socialists, and since he went on to win the general, that means they changed the results of the election.
Oh, right, that one. Well, don't blame me (I did vote for Roosevelt, but only because I didn't want my country to become Germany's puppet).
Anyway, the current primary system has mostly solved the problem of tactical voting. And it's ridiculous to hold grudges for an election that happened 12 years ago!
