McCain for one. He and his wife are multimillionaires yet he has been unwilling to make the sort of contribution to his own campaign that Mitt has to his.
McCain doesn;’t have to. He already did an entire campaign for name recognition, and has gotten about a hundred million dollars in free media since then.
When McCain leveled his false charge at Romney last friday, it was on EVERY news outlet. Romney had to fight to get any time at all to rebut the charge, and would have had to spend millions if he could have to run an ad to reach that many people.
The media loves McCain because McCain/Feingold makes all candidates beholden to them, as they are the only ones allowed to give candidates MILLIONS OF DOLLARS IN IN-KIND contributions, meaning free coverage.
It is his wife's money, she is probably too smart to give it to him.
