I don't think that this writer of a letter to editor in the Seattle Times is particularly fond of President Obama. But he does bring home an interesting point. The US Senate Republicans, by using the so-called nuclear option to get Neil Gorsuch confirmed to the Supreme Court could possibly come back to bite what is now the majority party, but may not be in as little as 4 years down the road.
Now I doubt that Barak Obama desires to be picked to serve as a Supreme Court Justice, but there is precedence. Look up William Howard Taft.
