"This is great!...It really shows courage!...What's the big deal?" Take a spin around right-wing radio and you'll hear the talking heads tripping over themselves to minimize the significance--or better yet, unconvincingly celebrate--the news that Sarah Palin's 17-year-old unmarried daughter Bristol is five months pregnant. Adding insult to injury, Palin likely lied about it all to Sen. John McCain when she was being vetted as his vice-presidential nominee. This ticket is coming apart at the seams. It was McCain's birthday last week, but he gave the Democrats one giant gift in Palin.
