Obama fires back, in an interview with Huffington Post's Beverly Davis. "I assume that if John McCain thinks that it's an inappropriate ad that he can get them to pull it down since he's their nominee and standard-bearer," Obama said.
(Not a great assumption -- and not a comfortable one the next time a 527 you'd like some distance from starts spending on your behalf.)
(And we wonder what Camp Clinton has to say on this subject. . . . )
The spot stays: "This is not about the RNC," state party chair Linda Daves tells the Charlotte Observer. "It is about North Carolina, our values and two Democrat candidates who are out of sync with the values of North Carolina."
More fun to come: Floyd Brown, one of the minds behind the "Willie Horton" ads, is taking on Obama, per ABC's Jake Tapper. "Quoting the Chicago Sun-Times calling the mayhem 'urban terrorism,' the ad points out that in 2001 Obama voted against expanding the death penalty for gang murders," Tapper writes.
"When the time came to get tough,' says the narrator, "Obama chose to be weak. So the question is, can a man so weak in the war on gangs be trusted in the war on terror?" The ad ends with appropriate subtlety: with an image of the World Trade Center rubble.
You'll hear this theme again: "The next critical primaries could be shaped by political dirty tricks from outside their campaigns," Carla Marinucci writes in the San Francisco Chronicle.
Clinton's win meant Obama-type money -- the Clinton campaign estimated that it would bring in $10 million online in the 24 hours after polls closed in Pennsylvania. "The boost in funds helped stabilize Clinton's campaign at a time when it was running a deficit and struggling to find the resources to compete with Obama in the next two states, Indiana and North Carolina," Sasha Issenberg writes in The Boston Globe.
"She will need the money for what is being framed as a do-or-die contest in Indiana two weeks from now," Peter Slevin and Shailagh Murray write in The Washington Post.
And she needs it to keep flowing: "We have to raise a lot of money," Clinton told a conference call of some 3,100 fundraisers Wednesday, per ABC's Kate Snow. "I know you understand this, but boy is it a tremendous hill to climb."
Mark this moment -- we cannot recall having read this sentence the morning after any previous primary: "The Obama campaign declined to disclose its fundraising total for Wednesday," USA Today's Ken Dilanian writes.
Meet us in Indiana: "Sen. Barack Obama is under pressure to knock Sen. Hillary Clinton out of the race and prove he can connect with working-class whites, while Sen. Clinton must narrow the delegate gap in order to bring in donations and keep her candidacy going," Amy Chozick and Nick Timiraos write in The Wall Street Journal.
They start on (roughly) equal footing: "With a demographic landscape that's well-suited to both Hillary Rodham Clinton and Barack Obama, Indiana is shaping up as the most consequential battleground of the remaining states," Politico's Jonathan Martin writes.
One of the many somethings to watch for: "Clinton could win the vast majority of counties in the state and still lose."
Even Republicans are excited: "Many in the GOP view it as nothing more than public relations nonsense, but the Obama campaign says 'Obamacans' are a growing political breed, much in the same way Reagan Democrats shaped elections in the 1980s," Brendan O'Shaughnessy writes in the Indianapolis Star.
