Enhances status of minority groups -- Far from decreasing the power of minority groups by depressing voter turnout, proponents argue that, by making the votes of a given state an all-or-nothing affair, minority groups can provide the critical edge that allows a candidate to win. This encourages candidates to court a wide variety of such minorities and advocacy groups.

In 2010, Republicans in Pennsylvania, who control both houses of the legislature as well as the governorship, put forward a plan to change the state's winner-takes-all system to a Congressional District Method system. Pennsylvania has voted for the Democratic candidate in the five previous presidential elections, so many saw this as an attempt to take away Democratic electoral votes. Barack Obama won Pennsylvania in 2008, but he only won a minority of the state's congressional districts. The plan later lost support.
