The first person I've seen connect the Palins with the term "trailer trash" over this situation is you.
That was the term used on this very website in re Jamie Lynn Spears, and not by me, either.
I've been defending the governor on another website against the charge in re Trig. I'm disappointed and frustrated by this news, which pulls the rug out from under that defense to some extent.
A number of posts here have compared it to, e.g., Bill Clinton, or the circumstances of BHO's own conception. Sorry, folks, that's using logic and playing fair. The Democrats won't do that (and this should come as no surprise!), but the bigger issue is that their obedient lapdogs in the MSM won't play fair, either. The "truth detectors" on our side will be working overtime to keep up with them.
The bigger worry for me, personally, is the ammo it gives to the anti-abstinence, pro-BC crowd. ("Look, your own VP, a Christian, couldn't keep her daughter chaste! It's impossible! Neener, neener!) The election, I'm not necessarily as worried about.
It's all over the DU site. One of the first posts there was "Sweet Jesus, John McCain nominated a white trash princess".
One thing that surprised me over there was the number of people who recognized how stupid this makes the democRats look when they have been claiming Bristol Palin is the true mother of the baby with Down's Sydrome.
