the party will be 'united' when she wins because all the people she's dissed-- youth, African-American voters, activists-- will support her because they have nowhere else to go, and The Stakes are Too High (aren't they always?) to stay home in November.  I think she'd get a really unpleasant surprise if she managed to scrape it out, because the youth & AA voters can survive another bad administration more easily than her 'hardworking whites' can, while liberal activist types are more valuable as volunteers and defenders than as voters, and most likely will do neither for her.
