That site is an eye-opener. It's is amazing how much the various lobbyist spend to get our representatives to act in ways that are not in our best interest. One thing that seems out of whack is that all the data I saw indicated a good bit more spent on Dems than Rebubs but in another page on that site I saw this.

“And the Republican outside spending advantage is even more pronounced: Republican-aligned and conservative groups so far this election season have spent $2.12 for every $1 that Democratic-aligned and liberal groups have spent, according to the Center’s analysis.”

I don’t know how that can be when all the breakdowns I see show more paid to Ds?
