Tom Edsall looks at the evidence. Money quote:
Since January 1, 2007, the former Massachusetts governor has spent well in excess of $80 million, including at least $17.4 million of his own money, paying media fees in excess of $30 million, salaries of roughly $16 million, and consulting payments of more than $15 million.
Among Romney's costly innovations this year has been putting more than 80 local conservative leaders in key states on his campaign payroll, in what amounts to a 21st Century revival of "walk-around money."
And still he struggles.
