Utter junk. There's no way 23% of each electorate hasn't made up their minds yet.
Not that RI matters much with how they allocate on the Republican side. 9 of the delegates (CD and RNC) are basically participation delegates if the three candidates finish > 10% and Trump doesn't get 2/3+ of the vote. They will split 3/3/3 for Trump, Cruz and Kasich for just showing up.
Then they'll apportion the 10 statewide with Trump (or the winner) with a 2 delegate edge (rounding down). If Trump is lucky, he'll get 10 of the 19 under the RI rules so long as all three major candidates clear the 10% floor.
