you said this -"But she is a terrible campaigner in that she comes across as arrogant, incompetent and worst of all, just not likable."
Is this really the issue that the 52 or so million people voted for Gore and Kerry? She has the same appeal that the other two have. IF they can get those people to vote for them then she can.
Your point is valid, to a degree. However, a large part of the Kerry presidential election vote was anti-Bush, not pro-Kerry. Kerry won the primary in large part because delegates thought they had someone with the skills to beat Bush. If delegates believe that of Hillary in '08 of course she will get the nomination, but I think it will become clear that she cannot, because of the characteristics I mentioned.
Gore was a much more likable person - kind of a buffoon, in fact, than Hillary and notwithstanding that did not come off as incompetent as her before he went off the deep end a couple of years ago.
