Read the poll here. Margin of error is +/- 4.5 for all respondents (registered Dems), +/- 5.7 for likely Dem voters.
From its summary:
The March 2008 Franklin and Marshall College Poll suggests that Hillary Clinton has regained the solid advantage she held over Barack Obama prior to February. Clinton leads Obama by 16 points among likely Democratic primary voters, 51% to 35%. Her lead among likely Democratic primary voters has doubled since the February 2008 poll, conducted February 13-18, when her advantage was seven points, 44% to 37% (see Figure 1). Mrs. Clinton leads among voters in virtually every demographic group, with the exceptions being non-whites and voters in Philadelphia (see Tables A-1 and A-2). The February survey showed the potential for a considerable amount of change in the race, but the March survey [which was taken from March 11-16] shows a less volatile environment. Fewer than one in seven (13%) likely voters is currently undecided, and most (85%) are “certain” about their vote choice, up from 72 percent in February. [my emphasis]
I’m not sure what to conclude, but it seems to me that each state so far, and we’re now past the half-way point of primaries and caucuses, has struck out on its own and defied following any pattern.
