(Image source: theverge.com) Wells Fargo upgraded Time Warner Cable Inc (NYSE:TWC) shares from market perform to outperform. The sole reason for the upgrade is Wells Fargo’s strong belief that regulators will approve the proposed merger with Comcast Corporation (NASDAQ:CMCSA). Currently, Senator Al Franken of Minnesota is waging a war against the merger. But Congress has no say on final approval, those powers rest with the FCC and the Justice Department. Comcast is using its powerful lobbying network in Washington to combat Senator Franken’s influence. I'll put my money on the lobbyist over the Senator!
