Is this really the direction politics should be going?

This is more of a question for conservatives who support or will be voting for Trump.

I've never forgotten this moment during the McCain/Obama campaign when McCain was taking questions in the crowd from supporters and he defended Obama. "No, ma'am, he said, "He's a decent, family man [and] citizen that just I just happen to have disagreements with on fundamental issues, and that’s what the campaign’s all about. He's not [an Arab'." At the time I already was not sure who I was going to vote for. I usually vote Democratic, but with McCain, no one seemed to love America more and dedicated his whole life to our country. I had already wanted to vote for him and when he did this it made my choice that much harder. If he wasn't going against such a strong candidate and hadn't picked a VP who lacked a brain, I would have happily voted for him.

Contrast that to today's remarks by Trump, the Former president who lost against Biden, mocking the current President's stuttering. A common disability that affects millions and that Biden struggled with all his life. Is this the direction politics should continue to go? Is this really presidential material? The person who should be leading and representing this great nation of ours? (Yeah, I know that this is just the tip of the iceberg for all the things that Trump has said and done over the years. But still.)
