Oh! I didn't know it has various meanings...sorry about that.:-|
I found "near sweep" in this paragraph:
======== In defeating Mitt Romney, the president carried Colorado, Iowa, Ohio, New Hampshire, Virginia and Wisconsin, a near sweep of the battleground states, and was holding a narrow advantage in Florida. The path to victory for Mr. Romney narrowed as the night wore along, with Mr. Obama winning at least 303 electoral votes. ========
Is this enough context? I hope I'm expressing my question clear enough this time!
