Need proof that it's tough running for President as a Republican this year?

Mitt Romney had to pony up $18 million of his own money for his campaign in the fourth quarter alone, which was two-thirds of the total amount he managed to raise.

To keep his poorly financed campaign afloat, John McCain had to take out a $3 million loan and secure it in part with a life insurance policy on himself.

And those are the top GOP candidates.
