And Mondale and LBJ, too!

Scott Helman, writing in the Boston Globe, finds striking parallels between Hillary Clinton's "red phone" ad and one used by Walter Mondale against Gary Hart in 1984. The non-missing link: Roy Spence, who worked for Mondale 24 years ago and is with Clinton now.

Over in TPM Land, Greg Sargent reports that Clinton honcho Mark Penn was asked whether the ad was based on Lyndon Johnson's infamous 1964 ad, which exploited fears of Barry Goldwater by depicting a daisy-picking girl followed by a nuclear explosion. Not quite sure I see that, but there you go.

You've probably seen Obama's response ad by now. But I'll bet you haven't seen this.
