As long as they seem to support your bias. And, yes, Democrat presidents have often inherited economic growth spurred by policies of the outgoing Republican President. If you studied macro economics you’d know that the effects of policies are seen years after the policies are put in place. Take Bill Clinton for example. He inherited a growing economy spurred by the previous Republican administration. While president he jacked up taxes which triggered an economic decline due to corporations moving production overseas where taxes were lower. Bush then inherited a declining economy triggered by the Clinton administration’s economic policies.
But, of course, People like you just look at the statistics showing how great the economy was under Clinton, completely ignoring what caused it.
When will Republican economic policies help the economy? They already have and will most likely continue unless nothing gets done due to our stalemate Congress.
