Scott Rasmussen has replied to Andrew Sullivan’s post about poll discrepancies which I blogged about earlier today: I am fascinated with those who see a big difference between our Job Approval polling and other polls. In fact, there is no significant difference. For a Democratic President, polls of all adults are typically going to show results about 3-5 points higher than polls of Likely Voters. That’s because some segments of the population that lean heavily Democratic are typically less likely to vote than others (i.e.–adults under 30).
