Has the "smart money" moved to Obama yet?

Let me start off with a definition:

When I use the term "smart money," I intend the term as in an investment framework (not that these people are smart for supporting Obama.) The "smart money" chases returns. In political terms, that would mean buying access, political support, or favor down the road. I would equate it to lobbying money, business money, and political ally/superdelegate support.

As Obama looks more and more likely to be the next President, you have to figure that these people must be out there trying to buy their place at the table, and ,similar to the endorsements, they're likely all starting to come in now.

Have we seen a big surge of "smart money" support for Barack Obama yet? Is that a part of the big dollars coming in now?

With their campaign themes, we can hardly expect the Obama campaign to trumpet a wave of insider money, but you have to figure that's going on, right?

We won't really know until May, but if this is the case, there's no way Clinton could compete past Mar. 4 based solely on the money.

(In superdelegate news, Rep John Lewis officially switched to Obama today, and the Clinton campaign, in a very telling reversal, is now imploring superdelegates not to commit, to hold their voice and their vote.

Later: ND Sen. Byron Dorgan for Obama?)
