The Fundamental Theorem of Politics
Theorem: When asked about why electoral promises weren’t fulfilled, a politician will accuse the opposition of obstructionism.
Proof: Most ideal policies that voters favor will have disastrous effects if implemented (in fact, more is true: most implemented policies are disastrous. But we don’t need so strong a claim for the purposes of this proof). However, politicians want to be elected so they have to cater to these figments of the imagination. The trick is to stall and distract once in power. Accusing the opposition of uncooperative behavior has two advantages. It taps into the natural hatred and distaste that one’s supporters already have towards the other side and for the opposition it allows them to rile their troops by saying “See, we were able to stop them!”.
