So a President is only supposed to cater to his constituents and to hell with the people that didn't elect him? After all, that's exactly what DumBama is doing.<quoted text>
The POTUS is elected to try to accomplish the goals that the candidate set forth in the campaign. The election determines which agenda is followed. Do you expect a candidate to run on a platform of being anti-abortion and then pursue a pro-choice agenda once elected? Your "he's not representing the people" charge is naïve and uninformed.
And if you believe that, then don't complain about the next President if he or she is a conservative and only carries out conservative agendas.
