It worries me a bit that Biden is not doing a Super Bowl interview. The Super Bowl is a golden opportunity to talk to tens of millions of Americans who never watch the news; why skip that opportunity unless Biden’s team is genuinely worried that he can’t pull it off. OTOH, I have to assume the Campaign knows what it’s doing. Maybe they are so confident that Trump is such a fatally flawed candidate that victory is virtually certain, so they don’t want to take any chances at all, despite the polling. I’ve looked at the polling, and Trump is only polling in the low to mid 40’s in almost all of them, so what I expect is that the people who don’t like the choice are going to break hard in favor of Biden, because while they may wish they have a younger candidate to choose from, they loathe Trump.
