It takes a village is more than a proverb or a book title - it will take a campaign that while the temptation is to make it about individuals - you need to show your campaign is inclusive without being groupthink and dynamic enough to show that where the US can be in the world is not a function of its MIC. Make it a Women's campaign that holds up half the sky.
Change the Format.
Make every Democratic primary a democratic forum on how the GOP sucks. Have each state party put up "favorite daughter/sons" as presidential primary candidates who can discuss using the primary debate format the state/local issues and trash every incumbent state level GOP candidate. Make these debates more like town halls and forums on GOP obstructionism - this is the kind of 50 state campaign that is necessary to win back Congress. Showcase what your Cabinet will look like and how the GOP's desire to kill off cabinet departments is not only counter-intuitive, but bad for the economy. Don't make the DNC convention a coronation, make it a series of caucus conversations with each state delegation.
This can't be centrist triangulating politics as usual because the democratic wing of the Democratic party already has a sense of HRC's record and ideological position. Of course it's still about electoral college votes and swing states and demographics and ad buys, but it has to be a lot better than 2008.
It was welcome, as well as expected, that Mrs Clinton would lob her hat into the ring. But with so much unknown about how she would intend to govern, it would be best if the Democratic primaries were fought with the sort of vigour – ideally by candidates that would include other women – that could force her to spell out her plans. Political contests are, almost invariably, to be preferred to political coronations.
