If the DNC decides that she is the one for them, they will make sure that there are no primary defeats, come hell or high water. Ballots will be found under the stairs in church basements for months to come. The voting machines will be set to default to her, the no-ID-needed voters will be out in droves.
Think about it. The dems could pull all kinds of mischief in the primaries, voting for the worst in the Republican Party. Then the dem power brokers could choose whomever they wanted as their candidate.
That's what I'd do if I were a devious *itch and in charge of the Democrats nomination process.
