How bad will America be if Trump became president

[abaris]

I simply don't understand why people think the president has any control over the economy.

Every head of state letting his mouth run amok, has a certain control. It's called international trust. You probably would consider withdrawing your investments from a corporation or bank where the CEO brags about making debt as if there was no tomorrow. Even more so if that person filed for bankrupcy before. It doesn't need to be the Americann president. It could the chancellor or Micronesia, if they have one. The only difference being that the possible Fallout wouldn't be as large.
