My apologies for coming off strongly recently. I've been sleep deprived and angry and for some reason I took it out on the Libertarian Party. I don't dislike the Libertarian Party and I've been extremely arrogant in my past few posts. My deepest apologies.
Noted.
I have occasion to offend friends when I have a lack of sleep. Like one time I posted some maps of the greatest winners in each state in the random map thread and made the comment "funny how the supposedly progressive FDR was second after Jackson in the South." AN embarrassingly retarded argument with Antonio later and suddenly I realized that having two hours of sleep affected my judgement.
Anyway, I do still have to point out the flaws in your premise, for mostly the reasons that Marokai listed. Hell, even in the early years of the republic non-duopoly elections had an effect on political parties. The Election of 1824 is perhaps the greatest example of political factions have a dramatic effect on the political landscape. Before 1824 the Democratic Republicans pretty much dominated American politics in the Era of Good Feelings. If the men who ran for president in 1824 simply sat by the wayside and did nothing in the interest of not causing their party votes, there is the possibility that we might be a legitimate one party state today.
I for one am thankful we're not.
