It's simple, direct answers, stupid.

Kevin Drum writes about why Hillary continues to be hounded by skepticism concerning her forthrightness, especially when it comes to Millennials. It has to be the #1 problem adversely affecting her likeability or favorability ratings.

As Kevin says, many believe she's just too "slippery." A reason for this sentiment is that Bernie gives very blunt and unequivocal answers to questions, whereas Hillary does not. Instead she offers very nuanced answers that often come off as seemingly disingenuous or hiding something.

Important: it's not that Hillary is actually hiding something or dodging or lying, rather that it just sounds that way. However that is the crux of her problem, the appearance of sounding evasive or waffling. And it's no doubt amplified with straight-talk Bernie as a foil. In fact, what better opposing candidate to shine a bright light on Hillary's trust problem than an older, frumpy, plain-spoken Independent?

Kevin discusses the Clinton burn out experienced by many of us. We became numb to the incessant witch hunts leading to nowhere. But Millennials were spared this nonsense, so what gives with their heightened skepticism?

I think the lingering email controversy is the problem. Millennials may not know the details concerning the Clintons in the '90s, but they hear things, they Google, they learn just enough to be suspicious -- and then this email thing comes along and it's game over for many. To them it screams poor decision process (I too wonder, why did she do it?!), leave aside legality. It's about judgement and that could very well have Millennials thinking if she did this then what would she do in office? Fair? Maybe, maybe not, but the damage is done.

And I've also heard some Millennials make the point of privilege (a very big word with Millennials), that anybody else would be going to prison for this email crap. True? Maybe, maybe not, but the damage is done.

So given her unfortunate history, unjustifiably hounded, etc., Hillary's decision to sidetrack emails was indeed a profoundly poor one. And it does not matter if it's technically legal.

If not for Bernie, Democrats would be suffering from low turnout in primaries. The youth vote went big for Obama and they're going big for Bernie, helping him win one of biggest upsets in polling history (Michigan), but will these Millennials show up for Hillary when it truly counts?
