You should probably read the other thread before throwing around that kind of judgment.hahahahaha...no surprise! bunch of idiots!
Actually, "Not sure" was a possible choice. It garnered 57% of the Republican response to the bombing question. You can see the poll language and results here (PDF, 102 pages, bombing question is Q38 on page 8).The issue is the stupidity of polls- especially one which does not allow "I don't know" as a response.
I agree that the polls are ridiculous.
