Breaking up the two party system is in and of itself the answer to nothing.
It astounds me that people speak of a third party without making any mention as to where it would be situated ideologically.
If, God forbid, it was situated right in the middle between Democrats and Republicans, that would leave us with THREE right of center parties.
I can't see ANY help from that.
Any third party that was actually viable would mean the end of meaningful presidential elections as nobody would get a majority of electoral votes.
All elections would be decided in the House of Representatives.
That's how we got Rutherford Hayes who ended reconstruction and caused Jim Crow and the Ku Klux Klan..
Even if the electoral college were displaced by a straight popular vote, there still would be no majority winner and the House would still choose the president.
Imagine the president that the current house would choose.
