First, in order to make a reasonable counterfactual, tell us how Fremont won. Just saying "what if he won" doesn't cut it.
Oh come on, you make it sound like there's a universal law in this forum where we absolutely have to point out how someone would win an election in such a scenario. I mean, what about Tweed's "What if Communist William Foster had won the Presidency in 1932?"-thread? Or the countless other threads which are vague about their electoral outcomes and just say "What if..."? Do they have to give detailed explanations as well?
Well I generally ignore most of those....
One can't just make a timeline and say "right here, history completely changed in the blink of a second," which is the effect of stating a major change in an election without providing the context in which that happened.
