That's why I thought. Why would you say that is? He's obviously educated and speaks with "facts" that have "references", but it just feels like the left does not like his facts/does not agree with the same conclusion his references reach.

I'm not big into politics but I don't really understand how two different parties can both use "science and data" to reach totally separate conclusions. Which one is lying/wrong?

As a programmer, it just doesn't compute. Input and output and all that.

Politics is informed by data, but it's not a science. There is no "right" answer (though arguably a lot of wrong ones).

Think of stuff that programmers do argue about. Type systems, databases, architecture, agile development, etc.

Logic is a great tool, but it's also more limited than people realize.
