OK, so what's the point, "I am an independent?"

The interview I watched on TV, she said that she wrote MOST of it herself. How long was the total speech? And how many lines did she supposedly plagiarize, two? Which sounds more plausible to you? A speech writer that put together a decent speech and possibly made a mistake, or a lady where English is a second language that claimed to write "most" of it herself? I googled the two lines and found multiple sources where others have used the same lines in speeches. I believe I posted them earlier. If it was copied, then it was copied by Obama also. "At this point, what difference does it make?"
