Although Levi Johnson’s 15 minutes of fame expired a few years ago the leftmedia keep dredging him up because (a) he’s guaranteed to make negative comments about Sarah Palin and, (b) Johnson’s appearance is a reminder that Sarah Palin’s underage daughter allowed this loser to have sex with (and impregnate) her, thus casting an unspoken aspersion against Sarah (and Todd) Palin who are Christians and espouse traditional morality. That their teenage daughter was rebellous, sneaked out of her parents house and had sex with her boyfriend was not something they could really control but the leftist hedonists that are repulsed by anyone who supports (and lives) traditional, Judeo-Christian morality revel in attempting to make Bristol Palin a figure of embarrassment to the Palins via the too-frequent TV appearances of the otherwise obscure Levi Johnson.
I’m sure there are boatloads of Dem political daughters who had unwanted pregnancies. The difference being they had abortions so the public is none the wiser.
