Josh Green notes how much leverage she now has in her righteous campaign against derivatives:
It doesn't seem like a stretch to conclude that Lincoln eeked out a win by convincing just enough voters that she was a Wall Street scourge. If her signature provision goes down in flames, she'll look toothless and weak, and almost certainly lose her seat. The bank lobby and the Obama administration (both oppose the Lincoln provision) may simply prove too strong and do the deed anyway. But their task got a whole lot harder.
