I have never seen so many republicans jump off the republican ship and defect to the other side. Donald Trump hijacked the party and zipped it into an ugly, dark direction. He will say and do anything to win. His erratic behavior and xenophobic speech pushed many over the edge.who knows if they will ever be back.
Donald Trump is likely hurting the Republican Party. The GOP could face losses in many Congressional races, as well as losing the presidential race. Trump's offensive remarks have alienated much of the electorate. Therefore, the GOP will likely suffer significant losses during the election. Trump is the only person that can undue some of this damage before its too late.
Donald Trump continues to demonstrate his unsuitability for the role of President by acting inappropriately and being offensive towards women, Mexicans and, more recently, the family of a war hero. By seeming to condone this type of behavior and not being able to reign him in, the Republican party is bound to be hurt as people will surely question its judgement.
Trump has spread a message of hate and shown that he has no tact or professionalism. He is easily bated into going off the deep end and says whatever he wants even if it is unprofessional or hateful. These are not characteristics of a leader. It reflects poorly on the Republican party that he represents them.
