Lucky for us in America the winning party becomes the majority ruling party. Imagine if we had a parliamentary system like Holland. The parties would have vowed (like in Holland) to shut Trump out.
Situations like Holland force the parties to work together in a bipartisan manner. Given the political divide we have now I don't think that would be possible here. We'd have a situation like Belgium where they have gone a year or more without a functioning government on more than one occasion.
