Video explainer on how the conservative minority punks Democrats and Republican moderates

Which ranked voting system are we talking about? With the system where you give a vote to everyone you want to win, then ultimately your vote will be applied to the candidate who can win in a head to head (unless you voted for the runner up). As they remove the “losers” as the votes are tallied. IIRC Australia uses this.

Ultimately this should allow for more moderate or at least a larger variety of parties. First past the post means ONLY a two party system is sustainable. And those two parties generally will start to skew more extreme as time goes on. And thus we are trapped in the “lesser of two evils” conundrum.

I don’t understand what the 2nd issue has to do with anything. Ones opinion counts at the time of the vote. Why should it matter if it changes over time?
