Not from the US, I think mail in voting can be secure, but I would not recommend starting this election for the reasons you mentioned and people need to believe voting isn't manipulated.

I know the US elections are pretty people centric, even though you are not allowed to vote the president directly. But if anyone could come up with an honest assessment of the problems the US is facing and offer some solutions or strategies, I think the chances to win are very high. You would have to beat building a wall towards Mexico.

Trumpers need to make peace with lefties and vice versa. Nobody will win otherwise anyway. I believe Biden will win the presidential election though. Not by merit perhaps, but because of demographic and inclination of voters.

If I recall the work of Democrats the last election cycle I see questionable FISA abuse and lying about Russia as the primary "achievements". I think there is room to do better.

What do I see when I look at Trump? I don't think he takes his presidency that seriously. He didn't kill minorities as some said he would.
