Oh, here we go again.

Joe Biden said that the Parkland shooting survivors called him while he served as vice president of the United States.

Oops! Except that the high school massacre occurred in 2018; Biden left the vice presidency in January 2017.

The gaffes have been piling up lately. The former VP blurted out he would accept “truth over facts.” Before that he uttered something about “poor kids” doing as well academically as “white kids.”

My goodness. The gaffes reportedly have Democratic voters worried about the former vice president’s intellectual stamina were he to secure the party nomination and then face off against Donald J. Trump.

Which brings me to my point. Are the Biden gaffes as serious as the Trump lies? Hah! Not even close, man! The Trump penchant for prevarication is much, much worse than the occasional blooper that flies out of Biden’s trap.

However … we have this problem with Trump’s incessant lying. We’re getting used to it! The Trump lies — which have totaled something far north of 10,000 since he became president — are becoming part of the dialogue these days. “It’s just Trump,” some Americans are saying.

Many voters don’t seem to care that the president cannot tell the truth if his life depended on it. He lies about everything. Big things. Small things. Important matters. Trivial matters. Trump lies when the truth wouldn’t hurt him in the least. He just lies.

It’s pathological, man … which is how I believe Ben Carson, the nation’s housing secretary, described it when he and Trump were competing for the Republican presidential nomination in 2016.

If Biden manages to win the Democratic nomination, all of us — you and me — can expect the president to seek to make hay over Biden’s occasional verbal hiccups.

My question is this: Are we going to hold the president to any kind of truth-telling standard? We damn sure had better.
