Good ever-lovin’ grief, Mr. Vice President.

Joe Biden went from declaring his intention to do what Donald Trump has done by refusing to honor a  Senate subpoena, to “clarifying” his remarks to essentially reversing himself by saying that, yep, he would show up to testify if asked to do during a Senate impeachment trial.

My head is spinning so rapidly I’m coming down with a case of vertigo.

Biden wants to be the next president of the United States. He’s the prohibitive favorite among Democrats still running for the office. However, keeps saying things that fly out of his mouth that require mid-course corrections. The subpoena matter is the latest.

I took him to task initially on this blog for telling a Des Moines Register editorial board that he would refuse to comply with a Senate subpoena; he said such a summons would distract the Senate from the issue at hand, which is Trump’s conduct as president. Republican senators want to question Biden and his son Hunter on their business dealings in Ukraine.

On one score, Biden is right; that is not the issue. At issue is whether Donald Trump abused the power of his office by soliciting a foreign government for a political favor and whether he obstructed Congress by demanding his key aides refuse to answer House subpoenas. To my mind, the answer is “yes” on both matters.

The former VP cannot play the game that Trump has played. So now he says he would comply with a Senate summons … if they ever get that trial started.

Great! Why didn’t he say that the first time?
