Not the original commentor, but the people I’ve discussed this with usually say one of 4 things. These aren’t necessarily my views, just what I’ve heard from others:

1. The government is too easy on crime and we grant people bail who are dangerous to release.
2. Gun control is a waste of time and money and isn’t tackling the real issue as nearly all gun crime isn’t committed by legal gun owners.
3. More housing needs to be made (note that both major parties seem to agree on this).
4. More infrastructure needs to be built to capitalize on our oil and natural resources exports.

I don’t think he actually said that though, the only quote I saw that included the word dumb was “It’s not in my habit to agree with The Wall Street Journal. Donald, they point out that even though you’re a very smart guy, this is a very dumb thing to do”.

The pain in his expression was the most relatable thing I’ve seen from a world leader possibly ever.
