NEW YORK ( TheStreet) -- Investors looking for a quick profit Thursday from Mitt Romney's debate performance last night may see a quick pop in the coal, oil, defense and HMO stocks, Jim Cramer told Lindsey Bell at TheStreet.com.

Looking at the larger political picture, Cramer said he's always voted for higher stock prices, which is why he feels that Romney -- who prefers a more hands-off approach to regulation -- would likely look the other way more often and thus be better for business.
