Economy 101 for partisans.
If the economy improves and your guy is in charge, he gets all the credit. If the economy starts to tank and your guy is in charge, well it's " a global economy, outside forces blah blah blah."
BUT, if the economy improves when the guy you hate is in charge it's "a global economy, outside forces blah blah blah", and if it starts to tank he gets all the blame.
