I'm baffled by the continued assumption that people vote according to their "bloc" at all. Correlation is not causation.
Who said people all vote according to their bloc? All the article I posted said is that Biden is very popular among black voters, not that all black voters support Biden. He has the support of about 44% in SC. Nobody said anything about people voting as a bloc. That wasn't at all my interpretation of the article. Still, certain candidates are popular among certain groups. I read recently that most of Mayor Pete's supporters are white and over 65. Most of Sanders' supporters are younger. That doesn't imply that any of these groups are all planning on voting according to their bloc, It's just based on surveys among certain groups of people.
Maybe I'm not reading you right. My primary point is that nobody really knows what will be the result of the primaries, as so many people aren't sure who they will support. And, many keep changing their minds. Don't you agree with that?
I'm interested in seeing if Bloomberg gets any support. My sister in New Jersey likes him, but I don't think many people outside of New York metro do. Does that mean that all New York moderates want Bloomberg? No, I don't think so. I've seen quite few celebrities drooling over the possibility of a Bloomberg candidacy, but my friends are not a all attracted to him and neither am I. This is about the nuttiest, most confusing primary mess I've ever seen. Maybe I just have more time to pay attention to it, or maybe it's more worrisome considering all I really care about is getting rid of Trump. I don't know. None of the candidates really impress me and that's a bit disturbing, as I'm not the only one who feels that way. On the other hand, I've seen commenters in major news sources say that the Democrats have a large list of very attractive candidates. Perception obviously varies from person to person.
This is going to be a mess if nobody gets the needed number of delegates, isn't it?
