Coming on the heels of a poll revealing that the nation feels the least safe since 9/11, a new survey finds that 67 percent of Americans believe another attack is coming, but this time from home-grown terrorists.

Rasmussen Reports finds that 34 percent say it is “very likely” that another strike will come within 10 years, 33 percent believe it is “somewhat likely,” and just 20 percent call it unlikely.
