They asked me who I was going to vote for, then said, "Did you vote in 2002?" Then they went back to a list of issues, and had me prioritize my most important issue (BTW, again, another stupid aspect of polling---they had "War on Terror" and "Iraq" as SEPARATE, which right away compromised the poll). Then they came back to "Did you vote in 2000?" In other words, they repeatedly, innoculously, got at my voting history and frequency.
And this was about 2-3 weeks before the general election. And it was M-D, as I later learned.
