Kaine has raised more than $22 million and has spent more than $4.5 million on ads, according to numbers from the Virginia Public Access Project. Meanwhile, Corey Stewart has raised almost $3 million and spent about $297,000 on ads. Stewart is succeeding in the cheaper arena of social media. "He was not going to have the kind of money that a candidate that is fully backed and has the enthusiasm of the Republican Party was going to have," said Professor Bruce Williams. "Tim Kaine has that." Professor Williams is the Henry S. Taylor Professor of Media Studies at the University of Virginia.
