The only time to really shake things up and really examine problems in the party is now, between elections, but he's definitely not offering any real help. If his 2-3 pet agendas aren't represented, he could care less.
I'd give Andrew a little more credit than that, but I would agree that 1) his vehemence about gay "marriage" badly distorts his perspective; and 2) that on social issues generally, he's on the side of the left. This seriously undermines whatever "conservative" credentials he has, and therefore lessens the value (and impact) of his advice.
I agree that a serious examination, even a "shakeup," is needed among the GOP and conservatives, and I agree that the time is now.
