But in the last twelve years Americans have begun to move further apart. There’s been a decline in the number of people calling themselves centrists or moderates (from 40 percent in 2000 down to 36 percent in 2011), a rise in the number of conservatives (from 38 percent to 41 percent), and a rise in the number of liberals (from 19 percent to 21 percent).3
Two to four percentage points doesn't seem like a big enough change to be significant. 36% moderate seems surprisingly high!
