Here's an idea. Instead of normalizing "both sides are the same" fuckery (i.e. the "bubble" nonsense) or crying over a loss how about you nominate a candidate people actually like in 2020, who isn't dealing with an idiotic scandal of her own design due to not giving a fuck.
I lived through the Bush years. Congrats, we have another republican president who most voters voted against. In fact we still live in a reality where republicans have won the popular vote ONCE since 1992. So stop crying and find another Bill or Obama, i.e. candidates who the base loves and will show up for.
Fuckin babies I swear
But isn't the problem that the Dems rely on fielding a charismatic candidate to win (and to win only the White House, mostly, since they lost a ton a offices in the last 6 years) ?
Finding a charismatic candidate is easier said than done, otherwise parties (and their militants who vote in primaries !) would field just that instead of Kerry, McCain, Romney or Clinton... It's basically reducing politics to luck of the draw or rolling a dice. Obama emerged as a contender fairly close to the primary cycle, didn't he ?
The real problem of the Democrats is that they rely on a "coalition" (a base) that need to come out in large numbers where it matters and can't be trusted to, it seems. They are confident that the demographic shift will favor them, but it's a future solution, not one for right now (and that's betting on keeping a strong hold on future latino votes). They need to widen their base and appeal to other demographics : they don't need to "win" those, just shifting a few points in their favor will do. It is also my understanding that for many offices in deep red land, Republicans run unopposed and that sound like madness to me.
In the immediate future, it doesn't make a lot of sense to pick theorical candidates for 2020 (we saw all the good a so called "deep bench" had in the GOP primaries...), Dems will have to focus on rebuilding on the ground and must mobilize around concrete issues like defending the ACA if needed.
