Lots of articles claim this but none offer any alternative. Your options are to be equally sectarian "back" or to attempt compromise, but compromise met with sectarianism is defeat. We saw this with Obama, every time he compromised on healthcare republicans just demanded more compromises. That's how he ended up barely passing Romney Care. I'm sure someone on the right can make the same claim about something the right compromised on and failed to progress.
I think this just has to keep going on and on until there are move voters in the middle than the edges or until voters get tired of deadlocked politics. And remember, people don't change their minds, they die and get replaced by new people. So this will not be fixed any time soon...
(Speaking from a complete US-centric perspective here) The goal is to hire electors that know how to work with others to reach solutions. In emergency situations this should be the case because fundamentally, and philosophically, we should all be striving for the same things (how we get there has historically been where the parties have diverged). But those events are very, very rare. I took from the article that the shared fundamental notion of what the US is and means is itself fractured and sectarian. Because of _that_ deadlock is an even more appealing thing to have happen. It's no secret that there are two Americas any more.
