Some news sources (like zeit.de, in German only, sorry) report that Trump could use a large number of lawsuits to keep the Electoral College from voting on Dec 14th. As I understand it, all legal battles have to be finished by then and an official election result has to be available.
If the Electoral College wouldn't be able to vote, the House would have to decide who to become President. In this case, which is said to have happened before in 1824 (why then?), the House would vote not with its members but with two representatives from each state. Since the majority of states are Republican, this would mean Trump would be the next president, having bypassed the actual election result.
Did I reproduce the scenario correctly? How would it look in detail? How realistic is it? What would have to happen in order for it to be successful?
