Interesting article about the Hillary Victory Fund and funding of the local parties. http://www.adn.com/article/20151221/outside-billionaires-fuel-joint-effort-between-clinton-alaska-democrats
It looks like some sort of agreement was reached in Alaska and several other states to use the local parties as a contribution laundering service to allow Hillary's donors to exceed the legal limits on contributions to the DNC.
It’s legal.
But it definitely isn't about supporting the local party. More about using the local parties to skirt what little remains of campaign finance laws.
