"It seems to me that the current Republican attacks on "vulture capitalism" (even though I wonder if there is any other sort) may help to polarise the "independent voters" against Romney (if he is then the presidential candidate) when the presidential election comes."

Romney was a real life Gordon Gecko from the first "Wall Street" film.

Romney has been promoting himself as someone who "knows how to create jobs" because of his experience at Bain. The Democrats had been planning all along to attack him on the basis that Bain Capital basically made its money by liquidating companies and destroying jobs.
The only difference is, when they use Republicans in the ads, the ads will get more credence.
