RNC Goes All In to Defend Wisconsin's Walker, but Where's the DNC?

John Nichols reports in The Nation, RNC Goes All In to Defend Wisconsin's Walker, but Where's the DNC?

"[RNC chair Reince] Priebus offers his “all in” commitment even though [Republican Governor Scott] Walker's campaign has a 25–1 financial advantage over [Democratic challenger Tom] Barrett. And that doesn't even count the millions coming in from the Koch Brothers and other national donors who are funding so-called “independent” expenditures on the governor's behalf.

What is the Democratic National Committee offering in return? Not as much. While the Democratic Governors Association and some other groups with party ties have been supportive of the electoral fight in Wisconsin, the DNC has been slow on the draw. Even now, after much discussion of the DNC's slow response, DNC chair Debbie Wasserman-Schultz says only that she hopes to come to Wisconsin for a fundraising event. Translation: She will make an appearance in Wisconsin where Wisconsinites will be asked to give money to the DNC."

If they're not going to support this campaign with money, I'd like an explanation as to why.
