Whether you are a Trump supporter or not, it's difficult to suggest that he is not radically different than other politicians and tremendously polarizing. Some see that as a sign of much needed change and other see it as a potential threat to democracy. Clinton was seen as largely a continuation of politics as normal so it would seem unlikely that there would have been large protests - perhaps more Tea Party protests (https://en.wikipedia.org/wiki/Tea_Party_protests) or an increased presence at the existing standing conservative marches (https://en.wikipedia.org/wiki/March_for_Life_(Washington,_D.... etc).
