Yes, he has a lot to swagger about. The only thing he has accomplished that isn't temporary(i.e. reversible when the next GOP President is elected) is Obamacare and that is the gift that just keeps on giving to the Republicans. All of his federal judge nominations are tied up in Senate committee. All he has left is executive actions that are only effective until he leaves office and then his successor can wipe them out of existence.
So yes, about all he has left is trolling his opponents.
