Sara Taylor Fagen and the Scandal Time Forgot

Halfway down in Peter Hamby's (as usual) excellent report on the moves Jeb Bush is making, we find this chunk of news jerky:

If that happens, it will be the final, hard slamming of the door on a scandal that Democrats investigated through much of 2007. That year, after they took back Congress—and with it, subpoena power—Democrats looked into the process of "voter caging," and whether the 2004 Republican campaigns flouted the law by sending mail to voters' addresses for the purpose of challenging their ballots. (If the mail bounced, but people showed up to vote, there would be a basis for asking if they were who they said they were.) The questions were raised by journalist Greg Palast, who obtained e-mails accidentally sent by the RNC to a fake White House e-mail address owned by satirists. At the same time, Democrats were investigating whether the Bush administration had acted politically in the firings of some U.S. attorneys (they serve at the pleasure of the president), sacking them because they wouldn't investigate voter fraud claims.
