Basically, the number of apportioned seats will stay the same. The idea here is to gerrymander two House maps which each max out the number of Republican/Democratic districts. Per tradition, the default factor in determining who gets each seat will be based on the 2008 election results, unless there's justification for why a seat is not safe for one party even if a candidate won it overwhelmingly (i.e. UT-4).
Remember that 2008 was a pretty Democratic year, so the baseline for pure tossup should probably be 53% Obama rather than 50-50.
I'll probably throw in some maps.
