President Obama's Gallup approval rating amongst liberal Democrats for April 2nd-8th is 87%.

62. But I think that applies even more to what someone calls someone else, no?

I mean, for example, here we have you saying that a wide swath of liberal Democrats are not actually liberal Democrats.

But I think it is quite likely that for the vast majority of those Democrats, you are clearly wrong (i.e, not even a close question).

So while what someone else calls themselves might be the wrong label, it is far more likely that the person disagreeing with that self-identification is wrong.

Your view is a textbook example of the "no true Scotsman" logical fallacy. It is actually very easy to do: all I have to do is say that 100% of liberal Democrats agree with me. If you disagree with me, all I have to say is "but that makes you not a liberal Democrat. So I'm still correct." But in the end, it is a good thing that you are wrong. Because the logical implication of what you are saying is that there are so few liberal Democrats, that there is really no reason for Democratic party politicians to take them seriously. You are wrong -- there is a reason to take them seriously, because they make up a large part of our party. But that fact only follows because you are wrong. If you were right, it would not follow.
