Perhaps it's because we don't forget or pretend that yesterday never happened, unlike a certain opposition party that is represented by the jackass, but would be more accurately represented by a pile of jackass excrement along with a sign that said 'democrats were here'.
The base of one of those two parties wishes to preserve and protect that magnificent world which our forefathers built, the base of the other wishes to destroy it and crap all over its smoking ruins while patting themselves on the back and insisting that it is progress.
In short: ****.All.The.Way.Off.
Do not pass go, do not collect 200.
