The number of Americans who are consistently conservative or consistently liberal has doubled over the past 20 years, Pew Research reported Thursday. Twenty-one percent are now consistent liberals or conservatives, up from 10 percent in 1994. In addition, those partisan sentiments are stronger among those who profess them. Also, the number of people in each party who view the opposing party in a negative light has more than doubled since 1994. They believe the other guy’s policies “are so misguided that they threaten the nation’s well-being.” Good luck governing.
