Shouldn't they leave everything on the field?

There are plenty of grounds on which to criticize RNC chair Michael Steele, but I didn't quite get this criticism from Gentry Collins, who resigned from the RNC on Tuesday:

In the previous two nonpresidential cycles, the RNC carried over $4.8 million and $3.1 million respectively in cash reserve balances into the presidential cycles.... In stark contrast, we enter the 2012 presidential cycle with 100 percent of the RNC's $15 million in lines of credit tapped out, and unpaid bills likely to add millions to that debt.

Maybe I'm missing the point, but what's the value in not spending absolutely everything during an election cycle? It's not like Republicans have nothing to show for it. Would Collins prefer that the GOP had a smaller majority in the House but more money in the bank? Does he really think it will be hard to raise a few more million dollars during a presidential election cycle?
