Grump is a habitual liar who prevaricates as often as he breathes. No matter what truths are uttered against him, he just denies. He constantly alters facts and states downright whoppers to support whatever point he is trying to shove onto the public at that moment.

As such, Biden cannot use reserve and tact when dealing with such a scumbag. Time to give Grump a taste of his own medicine.

For example, now that we know that
Trump: Americans Who Died in War Are �Losers� and �Suckers� - The Atlantic
Grump thinks Americans who died in war are losers and suckers, push this in his face. Whenever the military is mentioned by Grump, including at the Presidential Debates, just shove it in his face that he said that war heroes are losers and suckers, and that he doesn't even consider John McCain to be a hero because he was captured.

If anything related to women is mentioned, bring up that Grump has been accused by some thirty women of rape and sexual assault.

Take the gloves off and treat this bozo like he tries to treat others. Shove the truth into his face and call him a liar ad infinitum. Give him a taste of his own medicine. We can't afford to let him get away with another Presidency.
