If you're a teen father thrust into the spotlight because your fiancée's mom is suddenly a vice-presidential candidate, how to cope with the stress? For 18-year-old Levi Johnston, the answer is to chew gum obnoxiously on the stage at the Republican National Convention, even while meeting presidential candidate John McCain. Maybe the father to Bristol Palin's baby was just trying to prove that he really is a "fuckin' redneck " as stated on his MySpace profile. Palin's mom Sarah, who had just finished a well-received speech slamming Barack Obama, would not have appreciated further insolence from the young man who has still not publicly confirmed he will, in fact, marry her daughter as the McCain campaign claims. There's always an outside chance Johnston was merely following orders, the Republicans having gambled that a little cud chewing might play well among the "bitter" working-class whites Hillary Clinton once courted.
