New Jersey and Nevada were also split. Both candidates would each get a vote. To my calculation would be 300 EV for Romney if the House were to vote on the presidency with two electoral votes being awarded for each state won.
In a house vote electoral votes do not matter. The election is decided by house delegation. So if Cynthia Lummis votes for Romney that's one vote, as it it one delegation. If the California representatives all vote for Obama that's is still one vote as it is also one delegation. Therefore is Minnesota, Nevada and New Jersey have split delegations their delegation could not vote, hence the problem stated by this thread.
