"which could attach a $5 billion price tag to the most expensive midterm election in history"

If nobody can prove it, why not claim $50 billion?

Sources might not be known but the amounts spent on what can be tracked and they are being tracked.

EG spending for Republican candidates and Democrat candidates can be separated and tracked.

Funny thing, after the evil corporations fuck everybody out of their money, how are they going to sell anything?

According to Obama all spending is stimulus anyway so let those rich assholes sitting on that $17 trillion Bobert warbles about, spend some of it so it can trickle down.
