I do not think Sanders would destroy the US economically, nor would trump do even a tenth fo the things he says he would do.
Clinton is basically a candidate who will keep on obama's politics with another foreign political focus (she seems to be less opposed to more involvement of the US troups).
People who were fine with obama can vote for clinton withotu many regrets.
Sanders is more on the progressive side. Naturally he will not get half of the things through congress he wants to do, but he will at least try to chang eup some things.
That's fine too, people who are on the left but were not fine with obama and thought the democrats should not be as 'conservative' as they are today can vote for sanders without regrets.
Both of those candidates are absolutely president material.
Now...i do not have many nice things to say about the republicans.
Kasich would come to mind as someone who can at least give you the impression of being a president of a western nation (even with his quote about abortion in mind).
I could live with president kasich.
Now, Trump and Cruz are just people who really really like to win and be in the spotlight.
Trump would not necessarily destroy much. Some things done for rich people, then he would do whatever his advisoers tell him to do.
The US would embarass themselves with a clown for a term, but it's not like the US would instantly become hell. As mentinoed before: There is a congress.
Cruz is more dangerous than trump. He is a serious hatemongerer, he doenst just say these things, he means a lot of the things he says.
And he is more likely to have a serious harmful aggenda he is bound to get through with.
So all in all, i am very glad that i dont believe that you guys will have a republican president this year.
Trump effectively destroyed that possiblity (conspiracy theories aside^^).
Sometimes it hink the person who has most pleasure and fun with something should get it.
That's why I gave my 3DS i rarely played with to my little cousin who plays it everyday and has a blast with it.
And i think the person who will definitely fall into manical laughter after the election is done and the doors are shut is hillary clinton
