We are asking Iowa voters if they have been polled. Janet Mahan of Ames says she answered a Marist poll a few weeks ago and generally enjoys the experience. Frankly, it's been hard for us to find people who have actually been part of political polling — many, many Iowans tell us they screen their calls, or only have cellphones, or hang up immediately. So this serves as a reminder: Whenever you see a poll, think about the sample, methods, weighting, etc., etc., etc. -@jodyavirgan
