I’m not saying what Trump did wasn’t wrong. I’m not even saying it wasn’t a crime. I’m saying that we need to set the bar fairly high for the level of criminality we want to remove a president from office for. Otherwise we get into endless political squabbling and wasted time.

Clinton committed a crime when he lied under oath (nobody seemed particularly concerned about sexual harassment in his case). But the Senate decided it wasn’t crime enough to remove him.

Even with Jane’s murder example, what would have prevented a sufficiently motivated Congress from impeaching Obama for murder using some drone strike or assassination he authorized as a pretext?

I think there are eminently practical reasons for holding a US president to a different standard than a local highway commissioner. At least as long as they are in office.
