The economy is too complex to blame on the President. The public likes to relate the two, and for sure, there is some connection, but Obama is no more responsible for the recovery than Bush was for the crash. While linked, conflating politics and the economy can also be a mistake, just like falling for populists and demagogues. As much as either party would deny it, they aren't too far apart economically. Even Sander's proposals do little to the underlying base of the economy, and if he is elected, the economy will keep on doing pretty much what it wants—by itself, apart from politics. There's a huge gulf from anyone to Mussolini's corporatist structure. Plus, it's still before the primaries, and each side is focusing on highly salient issues with their base of primary voters. Once the first primaries take place and candidates start dropping out, the real issues of the election will come to the forefront.
