That's generally true. Presidents are routinely credited and blamed for things outside of their control, including things done by their predecessors. It's something you have to accept with the job. In this case, though, the President is taking actions designed to have quick effects. Presidents (of both parties) generally try not to do anything radical. (They promise to, then blame inaction on Congress.) This President is actually fulfilling his campaign promises, for once. So I think he will deserve a higher fraction of the credit and blame that he would have gotten anyway. The lag is shorter because he's bypassing the usual process for change, and is able to make much more radical changes with shorter term returns.
