Just about every head-to-head poll I’ve seen shows that Biden’s got about a 1% lead over Sanders in their vs.-Trump matchups. That’s not nothing, but it’s pretty close to nothing, and makes me look with rich skepticism on alarmist calls about all the Democrats who would vote Trump over Sanders. There just aren’t that many of them out there, as near as I can tell from actual polling.
But that doesn’t mean Sanders and Biden have an equal chance, because things can and will change.
As I see it, Biden is better than Sanders on background, but worse on campaigning.
Personally I much prefer Sanders’s background to Biden’s: Sanders has a long progressive history that warms the pinko cockles of my heart, and he’s been very consistent in holding these views even when it was politically disadvantageous to do so. A lot of the gossippy “nobody likes him” trifling is based on this, IMO: he refuses to play nice with folks whose policies are causing harm. Biden is a consummate nice-player, and boasts about how chummy he was with avowed segregationists.
That said, I think Biden’s past is gonna play a lot better in the general than Sanders’s. Sure, Biden made some fairly conservative moves over the last half-century; but those would only alienate people who already loathe Trump, and as we all know (or should know), the single most important item you can bring to the voting booth is a clothespin for your nose. Sanders, on the other hand, has some straight-up problematic shit in his past, especially that weird-ass essay on sex. That, combined with his Soviet honeymoon, are gonna be like cocaine-laced potato chips to the Fox crowd, and are a genuine weakness for Sanders.
However, on the campaign trail, Sanders is a 100% known quantity, the Big Mac of stump speeches. He is going to campaign tomorrow, and in March, and maybe in October, exactly the way he campaigned in 1990. He is solid and steady and reliable. Biden tomorrow might give a decent speech, or he might drop his pants to compare penis sizes with an Iowa truck driver, or he might tell attendees at a black church that single mothers and Cosby record player if they read more and Jim Crow wasn’t a friend but work across the aisle.
I’m biased toward Sanders, and I fully recognize that might color my conclusion, but I’d rather have a solid candidate with some weird shit in his past than an unstable candidate with a more conventional past.
