I stand by everything I said in this thread. E.g., this looks to be right on:
To be perfectly honest, it's not clear to me that there would be any damage to the party if she "abruptly" announced that she's not running. There would be a wide open Democratic field, and a mad scramble among numerous candidates to get in the race, but I don't think the resulting contest would necessarily damage the party, nor (as I said in this thread) do I think that whoever would emerge from such a primary would necessarily be a weaker general election candidate than Clinton. She looks like the strongest now because her name recognition is near 100% while most of the others are below 50%, but it seems plausible to me that some other hypothetical Democratic nominee would turn out to be just as strong.
Name recognition didn’t do much though. She nearly lost the nomination to a 75 year old Jewish socialist, possibly athiest, man who probably doesn't comb his hair.
