I noticed this when I was watching the debate live. I assumed it was a hankerchief, particularly after seeing Romney’s slightly red nose. I think there was a shot of him, somewhere near the end of the debate, wiping his nose.
The libs will stop at nothing to prop up Obama.
They HAVE to prop him up, because they’ve invested their own self-worth in supporting “brilliant” democrat politicians (like Sheila J Lee, Cynthia McKinney, and Marxine Waters).
