Do we really need a third presidential debate? What’s the point? To have another round of ugliness and continued disgusting performances by Donald Trump in his desperate and vain pursuit of the highest office in the land?

Why debase the presidency in this way? Perverse entertainment? TV ratings?

By this time, the country knows just about all it needs to know about the presidential contenders. What’s left to learn can come through paying attention to them as they conduct their campaigns, give their speeches, answer questions and explain their positions on the issues.

What gets us nowhere is the brawling, the insults and the bombasts, the lying gutter sniping that Trump brings to the debate.

Imagine: bringing Bill Clinton’s accusers to the debate and trying to seat them in the VIP seats so they could confront the former president? That was attempted by the Trump campaign, and it would have been successful if the Commission on Presidential Debates had not got wind of the trick and aborted it.

How low can the Trump campaign go? Limited only by their twisted imaginations.

The country has seen enough. Let’s not allow Trump to drag down one of our most honored processes any further.

For our national self-respect, pull the plug.
