It's kind of hard to "establish" the outcome of any "what if" scenario, but even as an admitted liberal and a person who is glad Clinton won, I think it is likely.I really hate to bring this up, but this has not been established, at least not enough to have changed the result of the election. Maybe you didn't mean it that way.
If you didn't, sorry...
But many scenarios are possible. Withdrawing and letting the remaining two candidates scramble for your votes might yield one outcome, while withdrawing and throwing your support behind another candidate might yield a completely different outcome.
