This new Harry Reid ad, narrated by a teacher who credits the majority leader with saving her job and that of 3,500 other educators, is about to join the already heavy rotation of political TV ads in Nevada. It’s another in a series of campaign ads that feature the Reid campaign’s primary message: “No One Can Do More” for Nevada. Sharron Angle’s message is, of course, just the opposite: Harry Reid does not do nearly enough for Nevada, and what he does do is not very good.
