If the Ukraine story was a dress rehearsal for a Joe Biden vs. Donald Trump matchup, the former vice president forgot to show up.
He's been an afterthought as the story unfolds, presumably scared to even discuss Ukraine or his son's roll in the country. This no-show strategy has left him a feckless afterthought and if his vanishing polls numbers indicate future results, a possible footnote in the 2020 race.
Now he calls for impeachment. After Warren, after Beto, after Harris.
The question: is it too late?
The answer: probably!
