Herman Cain's monthly fundraising shoots up to $5 million -- thanks to "smoking man" ad?

“Our donations online have shot up a lot since that ad,” says Mr. Block, who claims the weird, 56-second spot has now entered the eyeballs of at least four million people on YouTube, CNN, Fox News and other cable stations that have aired it repeatedly since Monday…

Mr. Block says the bulk of the campaign’s donations have come in online, averaging around $60 a pop. “The money we are getting is wildly beyond our expectations,” he said.

During the last two fund-raising periods, covering six months, Mr. Cain raised $4.7 million from donors and chipped in $675,000 of his own money. But that was before Mr. Cain took off in national polls and became the latest favorite of conservatives who aren’t wild about former Massachusetts Gov. Mitt Romney.
