I disagree. We have a huge segment of the population who are swing voters. They don't care about politics, don't post on political forums and don't really invest any time learning about the issues at hand. They vote only because it has been drummed into their heads that they have a civic obligation to do so. And when they vote, they vote superficially for the guy they'd most like to have a beer with or have as their neighbor.
Their votes count the same as yours or mine and this is the group of voters who decide elections.
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!
