The 6 Palestinians I know (from protests in the US), 2 in Gaza and 1 in the West Bank they all tell me they could care less Biden vs Trump, But if has to be one… with Trump there is more chances of change in the region, even at the cost of more lives. Besides, it will be far easier to regional countries and the European ones to distance from a link between Trump’s US and Israel.
third parties makes full sense. Of course you have no chance in the next few years but one of two scenarios will happen; 1) the people more and more open up the idea for the 3rd party and use it as a protest vote or 2) one of the duo-party system will try to capitalize on taking those votes by taking their main argument. No third party, no duo-party side has any incentive to remodel at all, they will just wait for the next cycle for their turn and things will continue as is. This is why the US political landscape has corrupted itself to the end.
