Yeah maybe you're right about Kamala's unpopularity being reflected on Democratic congressional candidates. Everyone's quick to point fingers about why the election results are the way they are (myself included of course), but it's honestly hard to say which factor had the most impact.
And I feel the same way about the electoral + popular vote thing. If the Democrats are going to lose anyway, a convincing defeat can at least be a wake up call for change. And this way we don't have to worry (much) about people claiming it was rigged.
The "hosting terrorists" part would be referring to the Houthi soldier he interviewed on stream. I personally don't have a problem with having controversial people on for stuff like interviews but the problem was more that Hasan was trying to make him seem more appealing and only giving him soft-balls.
The "blasting propaganda music" refers to him showing a Yemeni propaganda music video on stream to a guest and viewers. The lyrics were mainly about all the weapons and war supplies they wanted, and what they would use them for. It honestly was just bizarre and left everyone confused since there wasn't really context for showing it.
Not sure if the "Death to Jews" thing is referring to something specific or just that Hamas is very vocally anti-Israel.
