As in, Obama's appearance at Notre Dame sparked a “public outcry.”
From Politico:
But if the White House once hoped the speech was another way for Obama to reach out to this key constituency, the address instead is likely to be overshadowed by the public outcry, and in a state that Obama carried in the fall, Indiana.
Obviously there was an organized effort among some single-issue conservatives who opposed Obama's commencement invitation; who claimed the university had shamed itself by invited the President of the United State to address its graduates. But that in now way represented a “public outcry,” a term which suggests a widespread reaction.
In fact, in terms of the “public,” most Americans, and yes even most Catholics, supported the selection of Obama as ND's graduation speaker. ND students overwhelmingly backed Obama's appearance.
While we're at it, we'd ask CNN to define “backlash.” Its online headline from May 15:
Obama faces Notre Dame speech backlash
And USA Today to clarify “mixed”:
Mixed reception at Notre Dame for Obama
By all accounts Obama was greeted by the ND crowded with rapturous applause and an extended standing ovation, while three people heckled him. That's “mixed”?
Like Politico, CNN and USA Today conflated a minority protest into something much bigger and more widespread than it really was.
