THE HILL: Massie Primary Tests Trump’s Grip on GOP

President Trump’s quest to unseat Rep. Thomas Massie (R-Ky.) will come to a head Tuesday, as primary voters weigh whether there is room in the Republican Party for a lawmaker willing to openly defy the president.

Trump set his sights on Massie after the libertarian Republican publicly broke with the president on a series of high-profile issues, elevating an otherwise safe GOP primary into a personal political fight for Trump.

Republican strategist and ROKK Partner Ron Bonjean shared his thoughts in The Hill on what this race can show about President Trump’s hold on the Republican party.
