The cause? Apparently a bunch of Super PACs have launched a barrage of negative ads against Newt. Since Newt has no campaign funds to respond, it's basically a one sided fight.
First of all, as Josh Marshall notes, Newt is an easy guy to run negative ads against. He's a cretin and has been for a long time. You don't need to do opposition research on the guy. Ten minutes on Google will do the trick.
Second, you can't let these charges go unrebutted and Newt's lackluster fundraising is really becoming an issue.
Third, f**k you, Supreme Court. This is the landscape you gave us with Citizens United. As tawdry and unpleasant as the political season was before, we have only the faintest glimpse of what is to come. Massive ad buys of scorched earth rhetoric are on their way.
If this is how they treat Gingrich, imagine what is in store for Obama?
