Candidates who have been outspent have won before. I don't think you realize how weak a candidate McCaskill is. If conservatives and Tea Party people get behind Mr. Akin and raise money for him and volunteer for him he has a chance. Many people simply won't vote for McCaskill under any circumstances.
The big unknown is can Mr. Akin start running an intelligent, effective campaign.
Past history would say 'probably not'. Aiken is a walking, talking sound-bite for his opponents. In the past his verbal gaffs haven't harmed him in his races in an overwhelmingly conservative district. But McCaskill was running ads based on Aiken quotes before the rape comment. There is no reason to doubt that Aiken will provide her with more quotes over the remainder of the campaign.
Without the funds that would be very difficult.
Todd Akin is a great Representative, and will make a great Senator.
I have donated to his campaign and will continue to do so.
I, and many good conservatives, are standing with him.
Where does he get the money? He already owes bills he cannot pay. Yes, many who have less money and been outspent have won. But he has negative money right now.
