From NBC's Domenico Montanaro
Trying to play on a strength -- his experience in business --Romney is up with an ad in Michigan focusing on the economy and that America's growth is lagging behind that of China, the "Asian Tiger."
Instead of images of American economic woes or areas hurt by jobs losses, the ad is polished, fast-moving, optimistic -- the feel of Wall Street. (A ticker even appears at one point.) Romney vows to "level the playing field, lower taxes and invest in research and innovation, so that American companies can compete and win in the global marketplace and create jobs here.
"America must remain the world's economic superpower."
