Women have a tendency to vote Democrat and men a tendency to vote Republican. This trend seem to be continuing this year according to the Gallup Poll.
Male voters currently prefer Mitt Romney over Barack Obama by an
eight-percentage-point margin, while female voters prefer Obama over
Romney by an identical eight points. These gender-gap figures, based on
Gallup Daily tracking conducted July 30-Aug. 19, are virtually identical
to what they were four months ago.
