Since partisanship and ideological purity are increasing - with Republicans becoming more conservative and Democrats becoming more liberal -- a new third party ought to be emerging to represent those of us who are near the center
But in order for any such party to be viable, first-past-the-post must be scrapped and replaced with proportional representation and/or RCV.
The problem though, is that the current system as it's implemented doesn't really allow for third parties to breakout in any major way, beyond like maybe Trump going crazy if he somehow loses the primary.
It's not impossible, but it's very unlikely.
