Iowa’s caucus system means the Hawkeye State could hinge on who O’Malley’s supporters move to. 
 
The poll found 48 percent support overall for Clinton in Iowa, with Sanders at 40 percent and O’Malley at 7 percent.
 
“We’ve found Hillary Clinton leading in Iowa by 6-8 points in our last two polls,” said Dean Debnam, president of the polling firm.
 
“Bernie Sanders will likely make up some ground from Martin O’Malley voters moving toward him. To pull the upset, he will need large numbers of voters who aren’t currently registered Democrats to show up on his behalf Monday night.”
 
Clinton’s voters are the most committed of any Iowa Democrats, PPP also found.
 
About 88 percent say they are firmly dedicated to supporting her, compared with 74 percent for Sanders.
