See there aren't really any "winners" in politics, just temporary inhabitants of certain roles - roles which have vacillating levers for control, and ideologies.
So if Clinton wins, there is still the pesky problem of a possibly republican controlled congress (House more than likely) at some cycle - and then 4 years later doing it all again. This whole checks and balances thing isn't really efficient for getting things done (Madison made sure that was possible) for corporate interests, so if you need, say bi-partisan support for a bill that has a nice clause in in that supports (or doesn't) lets say H1B visa allocations for FY 2018 - then you need more than just the support of the executive branch. If the representative/senator that the tea party, or whatever the trump people are calling themselves, supports feel like [Insert Corporation] isn't on their side, then they can't compel the representative/senator to vote on their side and thus their power is reduced.
You need to work both sides, otherwise you aren't in the game.
