I also, too, don't think much of the Wise Old Men Of Washington because I've learned over the years that most of them are, at best, not wise. But also *normal people have no idea who the hell these people are.* Normal people barely know who John McCain is (was)!
People in DC have cable news brain. Probably now the young ones have Twitter brain, which is at least *better* than turning to Andrea Mitchell for wisdom. Appealing to the Hall Monitors or the Nonpartisan Referees or the Very Serious People has no appeal. "Well, jeez, I was going to vote for Trump but now that Colin Powell has spoken out against him...."
