It is a bit disheartening that some people adopt this win-at-all-cost mentally, as it is a reckless and dangerous frame of mind. It certainly is not the spirit of Democracy nor what the Founding Fathers intended. The US was built on a foundation of compromise and that is one of the pillars that have made it great; recall that George Washington only served two terms when he could have very likely been president for life and then, until FDR, presidents served at most two terms when there were no laws actually limiting them to two terms. That is not a win-at-all-cost approach.
However, it should be noted that not all Republicans adopt this win-at-all-cost position, some of them still believe in Democracy.
