( CNN ) Like a football team that must shake off defeat in order to prepare for the next game, Donald Trump has a short time to get over his drubbing in the first presidential debate and get ready for the next. He has, instead, been whininglike a kitchen blender about the moderator, the microphone and his adversary while continuing to draw attention to the worst parts of his performance.

Who

9) Abandon the Russians

Despite the evidence showing that recent cyberattacks against the Democratic National Committee and others emanated from Russia, Trump told the first debate audience, “She's[ Clinton] telling ‘Russia, Russia, Russia, ‘ but I don't.” This stand is consistent with Trump's earlier sloughing off of Russia's invasion of the Ukraine and his expressed admiration for Vladimir Putin. Because everything is personal for him, Trump likes Putin in part because Putin has said he likes him. Don't expect him to change his mind about the Russians based on the results of geopolitics. They are going to have to insult him personally before he does that .

10) Be nicer

In the first debate, Clinton pointed out his penchant for insulting people and Trump “was talkin about a” “somebody sitting on their bed that weighs 400 pounds.” After the debate, Trump decided to build veiled menaces about employing President Bill Clinton's sex scandal against her. Nastiness doesn't play well in a general election when a candidate must appeal to those beyond his or her base. However being nasty has always been a key element of Trump's repertoire, as shown by his feuds with Cher, Bette Midler, Rosie O'Donnell and others. Trump once told him that he doesn't respect most people because they don't deserve it. He is not likely to become respectful overnight.

Among Trump's advisers there is one, former New York City Mayor Rudolph Giuliani, who shares much in common with him. Like Trump, he poses as a tough man and wants the world to believe that his meanness is a virtue. He is also, like his nominee, a thrice-married man who feels entitled to criticize Hillary Clinton's lifelong wedding.
Consider Giuliani's persona and you find someone who understands Trump on a gut level.
After the first debate, he said that perhaps Trump should drop outof the two that remain. Trump's record of bankruptcies and abandoned projects demonstrates this is the one bit of advice he might be able to follow.
