Moderate Bait and Switch

When a candidate for political office, runs a political campaign portraying themselves to the public as being political moderate then where the candidate actually stands on various political issues in an effort to broaden their appeal to a larger group of voters. Upon winning the political office the candidate ran for, the new elected Politician then reveals themselves to the public to be a partisan hardliner who instead of working with both parties, toes the political party line that they are affiliated with. Often pushing for policies that the party they affiliated with wants regardless of what they pledged on the campaign trail.
