Conservative columnist Bill Kristol is very worried about the lasting impact on the GOP of Donald Trump being its nominee, suggesting conservatives may need to replace the “Party of Lincoln” with something entirely new.

“I now wonder whether the Republican Party itself doesn’t get so tainted by Trump that you don’t have to think about the possibility of a new party or a really radically somehow revised or reformed party,” Kristol said during ABC’s podcast “Powerhouse Politics” on Friday.
