We were doomed when Republicans decided that impeachment was a partisan tool and could not be used against Trump. They broke the system by abandoning their constitutional duties so we are now looking into the abyss.

The first time Trump used his power as president of a superpower to attempt to force a poor country to make up a fake investigation into his political rival. This is bad, basically unprecedented.
