And the Biden vs. Sanders dynamic has also played out on the trail, with Sanders in recent days going after Biden for his record on social security. Sanders' polling in Iowa and New Hampshire recently shows he is in a good position to win those states. Across all the pollsters who took a poll in Iowa in December or January and at least one previous poll, Sanders is up an average of five points from said previous poll. An average of CNN approved polls in January have Biden and Sanders tied at 21% and on top of the field. Like in Iowa, Sanders did well in New Hampshire in 2016.
