Ohio: Pre-Primary Polling

Baldwin Wallace University in Berea, OH released their pre-primary polling results (4/24-5/2; 811 OH registered voters; 333 OH likely Democratic primary voters; 323 OH likely Republican primary voters) as the candidates and electorate prepare to go to the polls next Tuesday. 
 
The poll appears to have a couple of methodological flaws.  First, the nine-day sampling period is too long and negatively affects reliability.  Secondly, there appears to be an over-sampling of females.  In a strange result on their political ideology question, more women then men identify themselves as holding particular political views in every category.  There are more women than men who are very liberal, liberal, moderate, conservative, and very conservative.  Taking the totals in each category, it appears that almost 59% of the sampling universe is female. 
 
That being said, in the Senate Republican primary, US Rep. Jim Renacci (R-Wadsworth) leads Cleveland investment banker Mike Gibbons, 24-10%.  This result is consistent with other published polls but tells us anything can happen on Election Day.  Seeing such a high undecided mark heading into the final weekend before any election is quite unusual.
