March FEC reports: Obama raised $40 million, Clinton half as much won't say

Update: I just saw on CNN that sources say Clinton raised $20 million. Reupdate: Ben Smith says the same thing.

Joe Sudbay notes the significance of the Clinton campaign's refusal to release its March fundraising numbers, concluding with the key political issue:

The superdelegates should probably be asking about the financial viability of the Clinton campaign. Remember, money was part of the Clinton campaign's inevitability -- and she finished February with lots of debt and unhappy creditors.
