Kasich Slams RNC's Priebus as a Podunk Political Hack After Priebus warned Kasich, others to 'get on board' with Trump By Newser Editors, Newser Staff Posted Sep 19, 2016 2:13 PM CDT 129 comments Comments Ohio Gov.

Well, one of those former rivals isn't having it. On official campaign letterhead, an adviser to Ohio Gov. John Kasich said the governor "will not be bullied by a Kenosha political operative that is unable to stand up for core principles or beliefs," report Politico and CNN. Kenosha is Priebus' hometown in Wisconsin. "The idea of a greater purpose beyond oneself may be alien to political party bosses like Reince Priebus, but it is at the center of everything Governor Kasich does," wrote John Weaver. What's more, he said Priebus ought to be thanking Kasich, who is currently working on behalf of GOP candidates he sees as endangered with Trump at the top of the ticket. The governor "is traveling the nation supporting down ballot Republicans and preventing a potential national wipeout from occurring on Reince's watch." Kasich and others, including Ted Cruz and Jeb Bush, signed a pledge to support the eventual nominee but have not done so.
