You do this in every thread for everything.
You have a theory, for example, "if young people don't vote, we can't win." From this theory, you find the data that backs this up, IE, the last two midterms we've lost, young people didn't vote, and then extend it out to fulfill your hypothesis, "not only are we not going to regain power, we're actually going to lose more power." Because young people don't vote. Not based on anything else, just this one bullet point you happen to have the bar charts for.
But this ignores 2006, coincidentally never mentioned by you (where young people also didn't vote), and that the trend has always been that the opposition to the president does better in midterms for various reasons that aren't "young people don't vote in midterms." Young people never vote. They never have. And yet liberals have found a way to win many, many, many times over the course of our history.
The same thing with healthcare
"The GOP unanimously supporters repealing the ACA!" and find a poll showing "generic repeal" is supported by 60%. While no actual repeal has ever polled over 50% for the GOP. But that's just ignored because everything is terrible and it's always terrible and just roll over and die right now I guess, might as well, right? See, the GOP supports the repeal!
You find this to be rational, I just find it as cherry picking data to support ridiculous pessimism.
