Something that deeply sucks about our federal election system and party philosophy

This was a close presidential election, and obviously we WON if you count the popular vote. But we LOST due to various quirks and flaws in our system, and just because of timing.

But now the winning party is granted immense power to do whatever they want politically, and the losing party is practically powerless. OK, fine. Elections have consequences.

Nonetheless, what pisses me off no end is that when the GOP squeaks through in an election, they push their extreme agenda, with no consideration to the Dems at all. Has Trump made one appointment that wasn't far right so far?

Whereas, it seems when the Dems win (Obama is a case in point), they try to govern from the middle and accommodate the right, they pick Republicans for cabinet positions and so forth.

WHY?????
