I wonder if health care will wreck our politics as much as abortion has. (Assuming it could be wrecked further.)
In the abortion issue you had a rogue Supreme Court usurp the rights of the legislative branch, and with Obamacare you had a partisan congress without support of the other party ram it through via bribes to its own members (i.e. “Cornhusker Kickback”).
Both issues attract a lot of single-issue voters. Both have only one of the political parties representing them. Supporters of both see it as a basic human right (to life, and to free universal health care) with the attendant moral dimension, making it much easier to see the other side as evil rather than mistaken.
