From Quinnipiac this morning, Sanders is within 19 in Iowa.
A summary of recent polling shows Sanders showing incredible momentum in Iowa.
I know a fair amount about primary polling history. This is the fastest I have ever seen a front runner like Clinton lose so much of their lead in Iowa. Clinton most resembles candidates like the following:
Reagan in 1980, who leads James Baker 48-23 in August of '79 (Bush, who ultimately won, was below 5)
Mondale in 83 (lead Glenn 55-17 in March of '83)
Hart in 87 (lead Jackson 65-9 in May of '87)
Gore in '00 (Gore lead Bradley 64-24 on June 4th of '99, he would get within 12 in Jan of '00 before fading)
Bush in '00 (lead 40-10 on June 4th)
What is good news for ALL democrats, is that Sanders rise is happening because people like him, and not because they dislike Clinton. Clinton's favorables have actually GONE UP in Quinnipiac poll. LET THIS PUT TO REST THE ARGUMENT THAT A PRIMARY FIGHT MEANS THAT CLINTON WILL BE HURT IN THE GENERAL.
