We could've spent more elsewhere if the Tea party hadn't nominated Angle. The Democrats are lucky. This year would be more of a bloodbath than it already is without the T Party's help.
Keep in mind that Lowden had problems of her own and Danny Tarkanian didn't have to deal with $14 million worth of attack ads. And if you think Ashjian is a problem for Angle now, just imagine how much of a nuisance he would have been if the GOP had nominated an establishment candidate. I suspect that Angle's tea party affiliations may have actually saved this seat for the Republicans.
