In fairness to Skipper, he was answering me and I was derailing. That broad swaths of this country have been persuaded that such things that he listed are 'extreme' is truly one of the major issues facing this country. Not saying Skipper is the issue. There are unfortunately tons who feel the same way. Unlimited Pentagon budgets aren't extreme. Proliferation of billionaires while the income gaps increase broadly not extreme. Climate change not extreme. Crap, I'm derailing again, sorry.
To get back to Biden--I do think his age is a concern. Not a 'oh my, I don't want to vote for him' because the alternative is flat out nazism. But as McConnell has shown, you can be fine one day (totally evil but obviously quite cogent) and then drop off the next. To me, that's concerning. Not concerning enough to give the Executive Branch over to the loony bin, but still troubling to me.
Barring an Eagleton moment VP choices don't matter in elections. Well, maybe Palin damaged McCain but Obama was going to win that one either way imo.
