On the Democratic side in Iowa Hillary Clinton has really reestablished her dominance, getting 57% to 25% for Bernie Sanders, 7% for Martin O'Malley, and 1% for the now departed Lawrence Lessig. Clinton's seen a 15 point improvement in her net favorability rating over the last six weeks, from +42 at 65/23 in mid-September to now +57 at 74/17. Sanders has continued to become more popular too, going from 56/20 to 62/20.
PPP's September poll had Clinton at 43, Sanders at 22, and Biden at 17. With Biden removed her lead became 50 to 25, so this represents a 7 point net gain for Clinton.
