I want to say at the outset that a) I believe the McCain’s ads have been much more dishonest than Obama’s, b) that the lying does matter (!) and c) conservative religious leaders ought to be smacking him but good for his violation of the 9th Commandment (8th if your Catholic or Lutheran).Having said that, if Obama is making an issue of McCain’s dishonesty, he needs be scrupulously accurate in his ads — and those on the religious left should chastise him when he isn’t. So far, they haven’t.The claim in this one that McCain wants to cut Social Security benefits in half strikes me as indefensible.
