(CNN) - Shortly after Hillary Clinton claimed a decisive victory in Pennsylvania Tuesday night, staffers for Barack Obama’s campaign sent reporters a memo in which they tried to argue once again that her win in the state had left the status quo fundamentally unchanged.
“Tonight, Hillary Clinton lost her last, best chance to make significant inroads in the pledged delegate count,” they wrote. “The only surprising result from Pennsylvania is that in a state considered tailor-made for Hillary Clinton that she was expected to win, Barack Obama was able to improve his standing among key voter groups since the Ohio primary.”
They said that Clinton’s lead over Obama with white voters had narrowed slightly, and her advantage among seniors had shrunk by nearly half - but that gap remained significant, at 24 percent. They pointed to Obama’s strength with Independent voters, a group that did not participate in Tuesday’s primary vote.
“The bottom line is that the Pennsylvania outcome does not change dynamic of this lengthy primary,” they wrote. “While there were 158 delegates at stake there, there are fully 157 up for grabs in the Indiana and North Carolina primaries on May 6.”
The Obama team had made similar arguments in the days leading up to Pennsylvania's primary, in which Clinton was favored despite being significantly outspent by the Illinois senator's campaign.
