> Oh no, political parties moving in response to the expressed will of the general public in a democracy.

Consider a very simple model of a two party system, expressing views on one left/right axis. Members of the population vote for the political party that is closest to their views on that axis. Political parties want to win as many votes as possible.

Under that model and those assumptions, if one party moves in a particular direction, the 'correct' behaviour for the other party is to move in that direction also to capture more votes, regardless of what the underlying 'will' of the general voting public is.
