So..... Can't get elected these days if enough financial backing can't be arranged. That's a big part of being "electable". Yes, Romney has personal wealth, but that in itself is not enough. He is also able to get donations amounting to many times more than he is willing or able to furnish from personal sources. If his personal fortune was the most important factor, then I would say the presumptive nominee would be Donald Trump. By most estimates his net worth is several times that of Romney's.
