Although Maine currently redistricts after years ending in a 2, might they change the law to do it early this time? First and foremost, Maine Republicans will want to protect their own majorities and could do so with gerrymandering. Secondly, it makes a single electoral vote a tossup or even R-leaning for 2012 and ensures it for 2016 and 2020. Finally, it's easy for them to justify as "synchronising with other states".
Well, the reason they don't do it in time for 2012 is that with their strange (and short) sessions and very early primary filing deadlines, they don't really have time do it in time for 2012. It wouldn't be *impossible*, certainly not for two federal districts that aren't going to be gerrymandered anyways, but if the necessary law change hasn't happened before the 2010 election it won't happen in time to affect this redistricting cycle.
