… Over the past several days, two major polls of Iowa have been released. At a glance, they seem to offer starkly different pictures of what’s likely to happen in next month’s caucuses. A poll from CNN, the Des Moines Register and Mediacom, conducted by Selzer & Co., has Sen. Bernie Sanders (I-Vt.) in the lead with 20 percent support. A poll from Monmouth University released Monday, though, has former vice president Joe Biden leading, with 24 percent of respondents identifying him as their first choice.
But both polls show a field with four candidates in the top tier. Biden’s lead in the Monmouth poll is a bit bigger than Sanders’s in the Selzer one, but neither is outside the margin of error. CONT.
