Barack's sustainability or Clinton's overrated database?

The Clinton campaign responded to reports of outstanding fundraising efforts by the Obama camp stating that the latter would not be able to sustain its efforts throughout the campaign.

No detailed reasoning was given for this opinion. My own impression given Obama's larger army of donors is that he has more reasons to be optimistic about future fundraising.

A lot of hoopla was made over Hillary's database of some 250,000 "supporters."

However, one has to wonder how many of these people in the database are actually supporting Hillary. Past contributions especially in general elections certainly is not a guarantee of support for the upcoming primary season.
