This is the practical outcome in a system where voters are forced to vote for the least problematic candidate out of a pool of two preselected politicians. Nothing will change, administration after administration, until the people are allowed to select their own candidates and the media promotes more candidates than just the big two.
Side note: a lot of people right now will be knee-jerking and wanting to respond to me that that's what the primary system is for. Wilding v. DNC Services Corp and the Democratic primaries that caused it should disabuse anyone of that notion. And trust me, if the Democrats are dirty dealing so are the Republicans.
