That's true about Jeb. Still, Biden's got a little fire to him in the way Jeb clearly didn't, but I tend to think Joe will probably sit this out now. 6 months ago I would have said it' 50/50, but somehow I can't get my head around the idea he's going to want to jump into the race in the face of this and defend it all for 18 months.
Which, of course, is the whole point here. The harder-left leaning of the party didn't give a crap about this out of an election cycle, but will now because they don't want the milquetoast reasonable old boring guy part of a successful prior administration running. They want either an elderly commie or a fresh-faced not-commie-but-left-of-Obama 40-something, either or. Cutting the head off the Biden snake this early is smart, because none of these people are going to survive an actual debate with him, that whole huge moderate center part of the country are going to think he comes off as the rational pragmatic one.
It's a weird one. He's "guilty" of this, it's just that there was 99% no ill-intent behind it rather more just "ancient guy that grew up in the 50s and doesn't really get it", which also doesn't make it okay either. But either way it makes sense his opponents in the party would seize on it. He's their best chance of beating Trump, but that doesn't really matter when you're committed to "free college! break up the banks! do away with all gasoline in 8 years!". Clearly Biden's not going to stand for that type of ****, so he's gotta go.
