President Trump jumped into campaigns in Michigan, Ohio and Tennessee on Friday, affirming his favorite candidate, which was crucial in other races.
In tweets at five-minute intervals and with the same language, Mr. Trump agreed with John James in the Republican Senate in Michigan and Troy Balderson in a special house election in Ohio, saying every man was "strong on crime and boundaries, loves our military, our veterinarians and our second change. "
A few hours later, again in the same language, he supported Representative David Kustoff of Tennessee against a primary challenger.
It is not clear how important his support will be for Mr Balderson, who has already won his primaries and is now facing Democrat Danny O & Connor, on 7 August. For Mr. Kustoff – facing a major challenge from George Flinn, a contender who has lost four previous congressional races but can afford to spend millions of dollars on his own money in his campaigns – it could be more valuable.
But it may ultimately be Mr. James who benefits most from the President's support.
Mr. James, a combat veteran and businessman, is in Sandy Pensler, another businessman, in an extremely close Republican primary. Whoever wins will challenge Sen. Debbie Stabenow, the established democrat Democrats, in November, and James and Pensler have worked hard to commit themselves to the presidency, knowing how influential his support has been for other candidates in this election cycle is  Mr.. James thanked Mr. Trump for his support on Friday and said in a statement: "President Trump has confirmed me because he knows that I have the experience of securing the borders from the battlefield to the boardroom protect Michigan jobs. "
Mr. For his part, Pensler said he was "disappointed that President Trump decided to support this election campaign" and stressed that he would support Trump.
"I have a campaign in support of The President's policy to reduce taxes, reduce regulations and protect our borders," Pensler said in a statement, adding, "My support for President Trump and his policies will be continued, and I believe that Republican voters will see a greater depth of understanding for the issues and will be a stronger voice for our large state in the US Senate.
The Trump-centered dynamics of the race is not surprising given the record so far this year: From Alabama and Georgia to South Carolina and Virginia, candidates who have been approved by Mr. Trump or have been considered Trumpian have won and candidates who have criticized Mr. Trump have been fighting.
Just this week, in Georgia, Brian Kemp – a conservative hardliner who ran ads promising to "gather" illegal immigrants and propose that with the gun in hand Every man who wanted to date his daughter should "have a healthy appreciation for the second amendment" – won a landslide victory in a Republican runoff, which in a way resembled the Michigan race. He and his opponent, Lt. Gov. Casey Cagle, both had tried to call themselves Trump-style, and Mr. Trump spoke at the last minute in favor of Mr. Kemp, which surprised some Republicans.
In the first half of May, Mr. Cagle led by more than 13 percentage points, but in the runoff, Mr. Kemp gained almost 40 points. And while Mr. Cagle was also hurt by the publication of a secret record in which he said that the primary was "who had the biggest weapon, who had the biggest truck and who could be the craziest," the support of Mr. Kemp's president could have been an even bigger factor. The Atlanta Journal-Constitution received internal polls from Mr Cagles campaign that broke its number just after the president's support of the president.
