An even number of justices does not necessarily mean a deadlocked Supreme Court. Most cases are not decided 5-4 (though it may be true that the most controversial cases are more likely to be decided that way).
I agree, especially in this case. Since it isn't a straightforward Democrats vs. Republicans issue, Kennedy or Roberts might go either way. Still, with our useless Congress, there won't be any new law, and even if there were, it could be struck down by a Circuit Court decision "approved" by a deadlocked Supreme Court. Ugh.
