I've probably seen this Boxer ad, "Outsourcing," the most. Apparently it started running about mid-September, and it's run a lot since then.
I think it's pretty effective. (Update: Here's more on the ad.) So is this similar one, "Workers," which started running 'round the clock a couple of weeks ago:
Both these ads underscore a recurring theme - the best case against Fiorina has often been made by Fiorina herself. Here she is on what's normally conservative cheerleading territory, Fox News, struggling to evade a reality-based question by Chris Wallace:
Wallace can be pretty hackish, but he does have his moments, and this was one of them. Like many Republicans, Fiorina mainly trots out slogans, but there's no responsible policy behind them. TBogg expertly summarized this Fiorina performance in "Carly Fiorina’s Underpants Gnome Budget":
1. Post every agency budget on the internet
3. Balanced budget!
It appears that Carly Fiorina is Christine O’Donnell with less Jesus and more work history.
