Here's a good example of such behavior ~ there are actually some school teachers who are honest and upstanding citizens. If "Education" is not a current issue in their area they'll vote for candidates on other issues. If education is THE topic of the day, you'll find them voting for their own self-interest.
That behavior might make it look like they are flip-flopping but they're not.
This is why it is necessary to identify the factions and go after those where you have a "wedge issue".
Obama has some advisors who know these things so they are working on a "wedge issue" suitable for Hispanics who may well be persuaded by Republican interests in private sector job growth. NOTE THAT ~ it's the JOBS Issue there just like with the 53% of unemployed recent college graduates. If you've been generally unemployed for 5 years after graduating, that's a really huge wedge.
The Democrats full well expect Republicans to exploit their advantage here!
There is no “middle.” There are just people who *think* they are, but who are ultimately not.
It’s an error to confuse “moderate” with “uninvolved.”
