Dems are clearly determined to keep Foleygate on full boil as long as possible: The national party has just sent out a release announcing that the Dem who'll give the response to the Presidential radio address on Saturday is House candidate Patty Wetterling, who's been a children's advocate ever since her 11-year-old son disappeared 17 years ago. As we reported yesterday, Wettering also has a scorching new ad up about about the Foley scandal.
