Dear Skinner...

78. Let us not forget this is DEMOCRATIC underground

and the we are supports to support Democrats on this site. If Skinner was sending a message, I think it's that one.

Clinton is, thus far, the only Democratic nominee and per TOS here on DU, we're to support that candidate. From the TOS:

Vote for Democrats.
Winning elections is important — therefore, advocating in favor of Republican nominees or in favor of third-party spoiler candidates that could split the vote and throw an election to our conservative opponents is never permitted on Democratic Underground. But that does not mean that DU members are required to always be completely supportive of Democrats. During the ups-and-downs of politics and policy-making, it is perfectly normal to have mixed feelings about the Democratic officials we worked hard to help elect. When we are not in the heat of election season, members are permitted to post strong criticism or disappointment with our Democratic elected officials, or to express ambivalence about voting for them. In Democratic primaries, members may support whomever they choose. But when general election season begins, DU members must support Democratic nominees (EXCEPT in rare cases where a non-Democrat is most likely to defeat the conservative alternative, or where there is no possibility of splitting the liberal vote and inadvertently throwing the election to the conservative alternative). For presidential contests, election season begins when both major-party nominees become clear. For non-presidential contests, election season begins on Labor Day. Everyone here on DU needs to work together to elect more Democrats and fewer Republicans to all levels of American government. If you are bashing, trashing, undermining, or depressing turnout for our candidates during election season, we'll assume you are rooting for the other side.

Emphasis mine.

The rules are clear on this and have been for some time.
