For almost an entire year Donald Trump insulted, berated, bastardized and scrutinized everything that wasn t a white, Christian male. Republicans barely flinched.Then he makes a comment about a Mexican judge s heritage when it pertains to his fraud lawsuit. Republicans lose their minds (and rightfully so).It appears that Trump s comments about Judge Gonzalo Curiel has hit a special nerve in one state legislator.The Des Moines Register has broken the news that David Johnson, who has served in the Iowa General Assembly for 18 years as a Republican, will be leaving the GOP over the party s  bigot  nominee, Donald J. Trump.Johnson told the Register: I will not stand silent if the party of Lincoln and the end of slavery buckles under the racial bias of a bigot. The now former Republican will be registering as a member of  no party preference,  and said he will never support Hillary Clinton for president. However, Johnson has also stated that he is not sure he will caucus with the Republicans in the Legislature, feeling that members of the GOP have become  too timid  to take on Trump and his supporters. Johnson did say that if a formidable Republican steps up to the plate and challenged Trump nationally, he may rejoin the party, but said: If Mr. Trump is the nominee, he becomes the standard bearer for a party that s on the verge of breaking apart. He simply cannot unify the GOP. If there is a profound split, I ll gladly rejoin Republicans who are dedicated to equality and justice for all, and let Trump lead his supporters over the cliff. And that s exactly what Mr. Trump will do. Johnson also knows how this will hurt him politically, but says he doesn t care, citing his record of often going against the Republican establishment in the state when it comes to education funding and Medicaid program.One thing is for sure   we will see many more Republicans follow Johnson s lead in he coming months.Featured image via Elijah Nouvelage/Getty Images
