Dozens of Republican leaders in Ohio are mounting a last-minute effort to urge former President Donald Trump not to endorse JD Vance in the crowded upcoming primary for an open Senate seat. A draft letter, circulating among Republicans…calls on Trump to remain neutral in the race. It was written following a news report that Trump was going to endorse Vance, a step the former president has not yet taken. Insiders say…the letter is a sign of anxiety among some Republicans about which candidate Trump may pick in advance of the state’s May 3 primary. Vance has come under particular scrutiny from some of Trump’s most loyal supporters for criticizing the former president in the past, something the Republicans highlighted in their letter. The letter, signed by GOP party leaders, including a slew of county chairs, tells the former president that “an endorsement that cuts against your support and legacy in Ohio will only serve to confuse or upset voters” and may even suppress Republican turnout in the fall.
