First time in history?

More and more Reps are publicly denouncing Trump and vowing not to vote for him. Has this sort of thing happened in political history?
I'm thinking folks will be talking about these weird events for years to come.

Members of the Republic party might be yelling, "What a revoltin' development this is!" (Can anyone name the person who often said this during his radio show and then TV programs?)

Please don't let me be the only one old enough to remember!

Yes! This is the first time in history we have had a presidential election like this. (That I can recall anyway.) The Republicans are denouncing Trump and vowing not to vote for him. If I recall correctly, the establishment Democrats did the same thing to Bernie. Of course the Republicans and Democrats are against Donald Trump. He is NOT a politician. He is NOT a smooth talker nor is he polished like a normal politician. He threatens the establishment on both sides of the aisle. This is why he was so popular in the primaries. Americans appear to be fed up with the smooth talking, spin spewing politicians! It sounds like a recording from 4 and 8 years ago.......Hillary says she is going to raise taxes on the wealthiest people in America. Republicans say they are going to lower taxes. That is the SAME thing they said 4 and 8 years ago. The Democrats had control of the Congress part of the past 8 years and the Republicans did part of that time too. Maddening that they all did so little in the past eight years.

This is a strange election indeed. Both Hillary and the Donald have very high unfavorable numbers. Most people do not like them but one of them will be our next President. I am still in disbelief that of all the intelligent, articulate, kind and caring people we have in America it comes down to one of two liars, one of two crooks and one of two people that a lot of people do not like or respect. And one of them will be in charge of America!
