After top Ohio Republicans tried to convince him not to endorse him, former President Donald Trump endorsed his one-time critic.

Ohio gets both brawn and brains from J.D. Vance. I have been great for Ohio and I won it twice. Trump said in a statement that they should keep going.

The Ohio Republicans tried to get the former president to change his mind as news of the endorsement leaked. Dozens of local GOP officials sent a letter to Trump, listing off the anti-Trump comments that Vance had made in the past.

The letter said that while we were working hard in Ohio to support you and Make America Great Again,JD Vance was actively working against your candidacy and that he referred to your supporters as racists.

The letter pointed out that Vance was a frequent critic of Trump. On CNN, he said that Trump's campaign was antagonizing a lot of the black voters. I'm a Never Trump guy, as Vance once said to Charlie Rose.

J.D. Vance may have said some not so great things about me in the past, but he gets it now, and I have seen that in spades.

He said he was incredibly honored to have Trump's support.

He was an incredible fighter for hard working Americans in the White House, and I will fight for the America First Agenda in the Senate.

There is a Republican Senate primary. There has been little independent polling of the race, but it shows that the race is not over.

A recent Fox News poll shows businessman Mike Gibbons and former state Treasurer Josh Madel in a dead heat. The margin between him and the former Ohio GOP chair was too close to call. The margin of error for State Sen. Matt Dolan was7%). The margin of error was 3%.

It is not unusual for Trump to give endorsements to candidates that are outside the GOP establishment and may not have ever held elected office. Sometimes it works out for the former president. Then-Rep. Before Trump endorsed Ron DeSantis, he wasn't the GOP pick. The star is so bright that he might challenge Trump in the future.

Sometimes it has risked Trump's political brand.

The former president had to withdraw his support from the Alabama Senate candidate after Trump endorsed him. Some Pennslyvania Republicans were upset by the former president's endorsement of Mehmet Oz. It doesn't help that Sean Parnell dropped out of the Pennsylvania US Senate race because he was accused of abusing his wife.

Trump takes his endorsements seriously and how his favored picks fare will be a key storyline in the upcoming elections. Senate Minority LeaderMitch McConnell has warned the GOP that their past nomination of flawed candidates doomed their chances at the Senate majority in 2010 and 2012
