By the looks of it, President Trump gave one hell of a performance at the Nevada State GOP convention Saturday night, where he was fundraising on behalf of Republican Sen. Dean Heller, who is running in what Real Clear Politics describes as a "tossup" against Congresswoman Jacky Rosen. And after last night, Heller definitely owes Trump a debt of gratitude for this gem.

In the middle of Saturday night's rally, Trump announced that he had devised a "great nickname" for Heller's opponent. Ever the showman, Trump hemmed and hawed for a few minutes as the crowd egged him on, before continuing with the big reveal:

"Wacky Jacky, you don't want her as your senator!"

Trump slammed "Wacky Jacky" for campaigning with "Pocahontas" - Trump's favorite nickname for Sen. Elizabeth Warren. The crowd exploded in wild applause, reminding us all why Trump's approval rating is at its highest level since his inauguration, despite the outrage over his "zero-tolerance border policy" and concerns that he might be leading the US into a damaging trade war.

Speaking of trade wars, Trump offered a few teasers on that subject as well, telling the crowd that "you will see things happen over the coming months that are going to really shock you."

Trump on trade: "You will see things happen over the coming months that are going to really shock you. Because for so many years we felt so badly, our jobs have been taken, our companies have been taken like we are a bunch of babies...Those days are gone. They're gone!" pic.twitter.com/57S3b0D5b5 — Aaron Rupar (@atrupar) June 24, 2018

"And we have so many things that we've done and so many things that we're going to do...nobody had any idea that we'd be able to do so much, so soon. A lot of them have had great starts, and I can tell you that on trade, you're going to see things coming over the coming months that will really shock you. Because for so many years we felt so badly, our jobs have been taken, our companies have been taken like we are a bunch of babies...Let's take the company, let's close the company and fire everybody, let's sell those cars back to America - we won't pay tax. Those days are gone."

Trump also urged the crowd to blame Democrats if their health-care costs go up (and also threw some shade at the ailing John McCain, who represents neighboring Arizona)...

...He also threw a few jabs at the media, calling them "the most dishonest people on Earth" and claimed that his administration had "already started building the wall in San Diego" (his administration is using $147 million from the omnibus spending bill to build a 14-mile section of the border wall).

"If they see any weakness, they will come by the millions. We have to have strong borders. We're going to have the wall."

Expect more performances like these, as Trump travels to states where Republicans are facing stiff mid-term challenges from Democrats, as the Republicans midterm strategy has essentially boiled down to using Trump to rally the base.
