Have you seen the federal government lately? It's totally understandable not to want that to be in charge of your healthcare.

In the 2018 poll the majority of Republicans (52%) actually supported it. There's just been a lot of effort pushing against it by most of the leadership in America (the media, the Republican party, most of the Democratic party leadership). The media plays a big role in this - they often only focus on the cost of one particular implementation of single-payer, and not on the 10's of thousands who die each year due to lack of insurance. There's no mention that the U.S. government is currently spending more on health insurance than the U.K. government spends on its single-payer system (and the total government and private spending in the U.S. is much, much higher).

And even though Democrat voters support this the most, the majority of Democratic Presidential candidates this year were opposed to single-payer and pushed some attacks on it that were mostly false (arguing that it removes choice). And a lot of polls on it will mention things many Americans view as negative (a single government run system) and not mention ones that they would view as positive (no out of network doctors, never being uninsured, never switching insurance, no medical billing issues, no healthcare bankruptcies, lower healthcare expenditures, etc.).

I am not sure how how people like their health care. It seems like every big company is moving toward High Deductible plan. Even Microsft has a high deductible plan. Even if you think you are covered there will be a doctors who you think is in network because you go to an in network hospital who really is out of network.

They like the quality of their healthcare - the "seeing a doctor and getting healthy" aspect. If the question was "do you like working with your health insurance" the answers would be different.

I've never met a single person who feels their health insurance is good or useful. R=close to zero if the hypothesis is the super majority like theirs.

> I think a significant part of that 55% doesn’t realize that Medicare for all takes away their health insurance.

Do you 'like' Walmart, the company? Or do you just want your groceries and don't really care what the store is called?

Of the people who come of age and are eligible for Medicare, what percentage of those people turn it down? I personally know of zero.

There seems to be a meme that the plan is to ban private insurance entirely? When even the UK system allows you to have it, it's just not grated huge tax breaks and is generally something only higher-paid professionals and those working for US employers have.

Health Insurance is not health care.

No one likes their health insurance. They like having health insurance given the horrifying alternative.

No one (except those on the ACA) gets to really "choose" their insurance either. Your employer offers a few plans. Those can change completely based on their whims.

Why would I care if M4A takes away my health insurance? Please, by all means, take it away! I don't care who pays the bills. In the last 10 years, I haven't been able to keep a primary doctor for a stretch longer than 2 years. Every year for the last 5 years, I have to critically look at my own health needs and try to guess as to what plan on the ACA is going to rob me the least. My taxes would have to go up at least $20,000 a year for it to even approach what I'm spending on a plan that I'm terrified that I might actually have to use.

They linked the results [1] (starts on page 402). 30% "Strongly support" and 25% "Somewhat support" so the net support is 55%. And among Republicans, the net support is 31%, I don't know what you mean by 'negative percentage points'.

Latinx are overwhelming swinging to Sanders (per your link), people of color swing Biden due to his riding on Obama's coat tails [1] (IMHO; he has no policies that benefit them with his "status quo" stance).

If Biden runs, Trump wins reelection. Not enough voter support for Biden besides older voters and people of color, younger voters will sit out before voting for Biden in a general election. That's not my opinion, that's what the polling data shows.

You see black people [on the ballot], you see Democrat, you vote straight party. You’re not used to seeing 10 damn candidates in the first place,” added Robinson. The menu of choices plays to Biden’s benefit because he’s a known commodity, Robinson said.)
