a) It has nothing to do with me or Canada. Someone else's headache.
Who is President of the US affects Canada a fair amount.
b) 4 years of non-stop entertainment.
I don't think the US backsliding away from democracy is entertaining.
c) The democrats need a kick in the nut to teach them a lesson that their position on Palestine cost them the election.
That's not the lesson they will learn from this, for a number of reasons.
1) The Israel Palestine situation is not listed by most voters as the main reason for their vote.
2) If you lose to a team that is explicitly saying the problem is that you were too weak on your support of Israel, then the lesson learned is that "Be more supportive of Israel".
3) The next election will not be about what was going on in 2024, but what is going on in 2026. What the public thinks about the Israel Palestine issue
then will be more influential than what the voters opaquely signalled in 2024.
Will some people draw the lesson "We should have been tougher on Israel"?
Sure.
But the idea that this is the obvious conclusion is ludicrous, because "what were the voters actually saying" is rarely clear.
Think about how many people still disagree about what drove voting shifts in 2016 and 2020? (And what lessons the GOP debated learning from losing in 2012 as well?)
