Far too many to name. From Ben Carson linking Hillary to the Devil to Chris Christie's mock interrogation. You know it's bad when the person who came out of that with the most dignity was Ted Cruz. I was hoping there'd be a bit more rejection of Trump but they openly embraced him.
If anything makes Trump dangerous, it's that there's a significant number of people who are behind his ideas and the Republicans seem to be ok with letting his ideas into the party platform. They could've denied him a nomination, it'd cost them the election but the party would come out looking more respectable and they might have salvaged some down ticket votes.
When attacking Clinton, they didn't even go after actual policy or legitimate political shortcomings.
It's like those memes Travis used to post in USA politics about Obama. You have a candidate with plenty of weaknesses that you could easily attack, but instead they're going to stick with Benghazi.
They also didn't even really praise Trump. The whole thing was based on "he's not Hillary".
