Personally, I don't think that moment came across as creepy. He's certainly no Sniffer Joe in the creep department.
However, the moment does indeed come across as a stereotypical artificial politician moment. Plus, considering the Dems' ever-increasing radicalism when it comes to abortion these days, it genuinely pisses me off to see them pretend they love babies ... Hence my admitted salt-ridden comment in my previous post.
The moment itself is so fake because of the timing in which he starts mentioning the baby: He does it right after he pauses in response to a lot of Trump supporters honking their cars at him. The honking clearly distracted him and pissed him off, and he tried to play it cool by pandering to someone in the crowd. Definitely a more successful response to the honking than Joe, at least. Haha.
