5th parag. from end:  

"With former New York Mayor Michael Bloomberg considering an independent presidential bid, the poll tested his favorability ratings among likely Republican and Democratic caucus-goers.
..........  
The findings highlight some of the hurdles facing Bloomberg should he decide to enter the race. The former mayor isn't well known in the state among the most motivated voters in both parties, with 41 percent of likely Republican caucus-goers and 57 percent of likely Democratic caucus-goers not knowing him well enough to share an opinion.
........  
For those who do have an opinion, 50 percent of Republican caucus-goers have an unfavorable view, versus 

just 9 percent who hold a favorable opinion.

Among those likely to attend the Democratic caucuses, that split was 26 percent unfavorable to 

17 percent favorable.
.........  
Bloomberg was a three-term mayor of New York, twice as a Republican and finally as an independent, and is the founder and majority owner of Bloomberg LP, parent of Bloomberg News.

The survey, conducted Jan. 26-29 by Selzer and Co. of West Des Moines, Iowa, included 602 likely Republican caucus participants and 602 likely Democratic caucus participants. It has a margin of error of plus or minus 4 percentage points."...
