Obama will almost certainly win. He won't immediately move to constrain access to guns, because he has other priorities, and because his majority in congress will include a large number of "blue dogs," who are at least superficially pro-2nd. But the overall strategy here is to "relabel" overtly socialistic and statist ends as something else. So they've relabeled socialism as "social justice" and "multiculturalism" making it exceedingly difficult to place a proper label on Obama even though his familiars include former domestic "new left" terrorists like Ayers and Dorhn. It's really difficult to argue against "social justice" or "multiculturalism" and even more difficult to define.
So they won't attack 2nd Amendment rights frontally. They'll use a stealth strategy, relabelling the issue in some critical way, constraining access to amunation rather than guns, etc..
Obama will almost certainly win. There's such a tide in his favor at this point, as a result not only of the relabeling of leftist idealism, but due to a kind of "perfect storm" of economic and finance issues, that holding on to the chance of on upset amounts to a kind of denial.
You'd be better advised to attack the relabeling program directly. You may not win a huge number of converts this way, but you should be able to at least "hold the line" awhile. Moreover, if "social justice" is an ambiguous term, one could appropriate it, just as the "progressives" appropriated the term "liberal." That's the Achilles Heel of their strategy.
Sorry. Didn't mean to distract.
