Upside for the opposition: if/when the economy implodes, dems can't put blame on reps w/o looking really stupid (not that they won't try).
downside for opposition: if they succeed, they'll have a shot at at least 4 more years and then some in order to achieve their goals. If spectre of PA gets elected as a dem (as if he weren't that all along anyway

), that will only solidify dem majority.
@mimartin--nice cartoon and good point.
