Eve Fairbanks hits the nail on the head in her latest column in the Washington Examiner.
The Democrats have that problem big-time. They never got over the 2000 election, and now, they are getting even angrier as they find out that being in power doesn't mean the problems will be solved easily.
That said, on the right, there is a need for serious anger-management work as well. On immigration, tempers are extremely hot, some ugly stuff has been said, and now, neither side can really back down.
Too bad we can't impose a 30-day cooling-off period for debates.
