Over in the U.K., Gordon Brown's politcal fortunes are in the dumper because of an unfortunate remark to an old dearie (he called her a "bigot"). Compare that with what happened to Obama. When he was running for the highest office he dissed not just one voter but an entire segment of voters, who he claimed are "bitter" and "cling" to their "guns and religion"--and it didn't hurt him one bit.
Conclusion: Some politicians are made of Velcro. Brown is one of them.
