Here's a good snippet I cut from Daniel Henninger's Wall Street Journal column yesterday.
. . . . By now, the Democratic Party's ideas are largely generic. Everyone noticed that the Democratic presidential candidates were largely singing from the same script. Health care, public schools, green energy, the eternal shafting of the middle class, the unions, protecting Social Security and Medicare. This common script means that the Democratic primaries are largely an audition. The candidates are reading for a role. The lines are known.
