Wikipedia lists the US population as around 325 million and EU population as around 510 million.  Are there some big member states you aren't counting in your claim (excluding both economic output and population)? 

I said the Soviet Union, not the European Union.

People who judge their friends based on political differences are not true friends.

A person can be convicted to trust a politician or another. Though you may see Trump as a racist, misogynistic, cruel and selfish person, someone else may find him entirely the opposite.

It often just depends on the angle you are looking at something. I have listened to Trump and Hillary speak, and I can tell you I understand now a lot more deeply why Trump says the thing he says, yet only two months ago I thought the man was a complete idiot.

I had a dialogue with two girls (I know, bad move but I just wanted to talk about the things I had been listening to), and both were so disgusted by Trump. Yet both told me they barely knew what he was actually saying by listening to him. They got their perspective from the media.

So while in one case a person could have a completely hateful view about a candidate, in another case they might see it differently.

And that's OK, it doesn't make the person evil or to have poor values. It just means they see the candidates in different ways. And the thing America needs most is open-mindedness. This year's elections  prove that people are very closeminded, more than ever. I think Trump has been completely misunderstood and that's just the way I see it.

If any friend of mine likes me less for it, they are not my true friend.

Well for starters you're trying to compare Adolf Hitler to simply voting in an election. That's a big leap.

Even if that were the case though, again I wouldn't care. They have every right to vote or support whoever they want. While I might not agree with it, i'm not going to end a friendship with them or look at them any differently just because they have a certain opinion on something that is different from mine. Just because i'm friends with them and they support something that I don't, it doesn't mean I support it just by being friends with them. I became friends with them for the person they are, not what their opinions or beliefs are. 

Otherwise what is the point of interracting with people if you're just going to not be friends with them if they don't have the same exact view you have on something, since everybody in the world has their own opinion. 

I believe in the saying "Actions speak louder than words". 

And by what measure do they have anything resembling 87% of the economic output of the USA?

Also, is there an easy link to showing that the former member states of the USSR do indeed have population about the same as the USA?  Russia itself is less than half.   Never mind. 

See the way I see it, part of the "person they are" is their values. I wouldn't want to affiliate with somebody whose values were repugnant to me.
