The difference between Democrats and Republicans is that Republicans actually do, despite the polarized political climate, hold some principles that transcend their partisan agenda.
Which is why you see some concern emanating from the GOP about whether President Trump tried to obstruct the investigation into ties between his advisors and the Russians, and why you saw absolutely none out of any Democrats the times Barack Obama acted to obstruct justice. And of course, no outrage then from the mainstream media either.
Obama sent strong signals to police and the judiciary about how he wanted certain cases resolved. While he was more subtle about it than the bull-in-a-china-shop Trump, his desires were no less clear.
Let’s start with the most egregious example, his attempt on April 10, 2016, to influence the decision on whether to prosecute Hillary Clinton for mishandling classified information by setting up her own email server.
