Ben Nelson Blasted For Voting With GOP On Bank Reform Filibuster

The Progressive Change Campaign Committee is launching an online ad campaign targeting Sen. Ben Nelson (D-Neb.) for voting with Republicans to block debate on financial reform legislation on Monday afternoon.

Nelson was the only Democrat to break with party ranks and support a Republican filibuster on the measure, which failed to get 60 supporters in a 57-41 vote.

The ad offensive against Nelson charges the Nebraska Democrat with voting on behalf of Wall Street and against taxpayers. Here's how the group behind the attack supports its claim:

Nelson has taken over $400,000 in campaign cash from the financial industry.

Every 1,000 spent on the ads can reach about 100,000 people in Nebraska. Final ad buy will be in the thousands of dollars -- and depend on online fundraising.

The Progressive Change Campaign Committee also unveiled a petition shaming Nelson for putting the interests of big banks ahead of taxpayers and voting for the status-quo. Here's an except of the petition from the group's website:

"SHAME ON YOU, Senator Nelson, for putting Wall Street ahead of taxpayers. Your corporate campaign contributors may be happy, but you did not do the people of Nebraska proud."
