Nice to see it so close from one of the three A+ rated pollsters.

This poll only included people who said they would definitely attend or probably attend the caucus, showing that Sanders' support will not evaporate come the time to actually vote. When asked if they would attend the caucus 63% of people said yes and only 37% said no. This is up from last month (48% yes, 52% no), and is the highest numbers that have been seen during all of the polls this election cycle.
Amongst those polled 3% said they attended a Republican caucus in the past, 61% said they attended a Democratic caucus, 9% said that they had attended both a Republican and Democratic caucus in the past (1% not sure). The shocker comes in with the number of first time caucus goers at 26%. Likely this helped boost support for Sanders, as his support tends to be younger. December showed a similar 25%, but the January numbers are the highest this election cycle.
Bernie Sanders leads Hillary Clinton 72-71 for combined first and second choice (O'Malley gets a combined 15%).
Amongst supporters for Hillary Clinton and Bernie Sanders, 70 percent of people said that they had made up their mind vs 30 percent who said they could still be persuaded (Clinton is actually 69-29). This is only a slight rise for Clinton, with a change from 64-35 the previous month, but Sanders has increased from 55-45. Both of these increased from mid forties in October. When you look at the overall Democratic Party, the numbers are 59-40.
There were no numbers for what the demographics polled were (age, sex, race, etc.) which is annoying.
