In addition to the Monmouth polling sample under-representing minorities by a factor of nine percentage points in comparison to total population, the weighted numbers also give GOP primary voters a boost. The “primary voting history” is reported at 47% for Republicans versus the Democrats’ 36 percent, yet the latter turned out in greater numbers for the June 13th intra-party elections.
Overall, the sample yields 30% self-identified Democrats and 27% Republican, with 43% considering themselves independent. This division skews slightly Republican, as the actual Democratic advantage is a bit larger. Without party registration the actual numbers are difficult to determine, however. Virginia is one of 18 states that do not require voter registrants to state a political party preference or membership.
