The discomfort of red state Democrats torn between their own political interests and those of the national party has been multiplied by the sudden detonation of a Supreme Court battle in the middle of a midterm election campaign - and Trump is not wasting his golden chance.
"Democrats want anarchy, they really do", Trump said, adding that he intentionally called the party "the Democrat Party" because "Democratic Party sounds too good".
Trump's eldest son, Donald Trump Jr., opened the rally to deafening applause and quickly went on the attack against Tester.
Tester's campaign published a full-page ad ahead of Trump's visit thanking the president for signing 16 bills that Tester sponsored or co-sponsored.
"Do we have an incredible president or what?" Trump's message will influence his decision, he said. "We're people", he told the rally in Great Falls.
Trump nearly immediately lashed into Tester, the two-term Democrat, who he blamed for derailing the April nomination of Navy Rear Adm. Ronny Jackson to head the Department of Veterans Affairs. "I'll see what Trump has to say and how he delivers his magic words". I put him into the world of politics. "I believe him. Jim Jordan is one of the most outstanding people I've met since I've been in Washington". Ever the fan of Twitter nicknames, he's dubbed her "Pocahontas", referring to an accusation popularized by Warren's 2012 Senate race opponent Scott Brown, who said the senator of falsified claims of Native American heritage in order to gain a teaching job at Harvard. You know? He's the one, ' Trump said, recalling Jackson's commanding performance in the White House briefing room describing the president's health. I promise you I'll do this, you know those little kits they sell on television for $2: "'Learn your heritage", Trump bragged to the crowd, saying if Warren brought up her Native American heritage, he would respond by pulling out one of "those little kits". "To the fake Pocahontas, I won't apologize", he continued as the almost all-white crowd roared.
"Let's say I am debating Pocahontas", Trump surmised. On Thursday, the Department of Health and Human Services announced it would conduct DNA tests as part of the effort to reunite migrant children who were separated from their parents as a result of the White House's "zero tolerance" immigration policy.
Today, I am going to take a different approach. "We have to do it gently". He also mocked former Vice President Joe Biden, California Rep. Maxine Waters, and repeatedly referred to Democratic Massachusetts Sen.
"I have criticisms of our generation". "We will gently take the kit and slowly toss it hoping it didn't injury her arm. Even though it only weighs probably two ounces".
Trump also pledged he would give $1 million to a charity of Warren's choice if she took a DNA test.
After the speech, Warren, D-Mass., hit back.
"Maybe you should focus on fixing the lives you're destroying", she tweeted.
He repeated slams on key Democrats, including Sen.
But Clinton and Tester weren't the only Democrats who drew fire from Mr. Trump on Thursday. "You can right that wrong in November", Trump told his adoring crowd. "We're going to be out there fighting for Montana".
Trump also mocked President George H.W. Bush's slogan during his rally.
Some of the Montanans who made their trip to Great Falls for President Donald Trump's rally on Thursday were there to be critical, not supportive. "You wouldn't think it would play very well out here". He called out Tester for his abysmal voting record, ticking off several issues on which Tester voted against the president's agenda.
