That's happened before (look at articles on the "era of good feelings").

What happens is that factions develop along a new politically-important axis which have different answers for a new pressing problem, and the moderate party bifurcates into two.

Because artificially making the 'other side' look evil is an effective way to win elections. If you can find some way to make the other side look bad (no matter how artificial, see Hillary on the Cubs/Yankees issue), then you win.

Huge incentive to find any division.
