It's unclear if there's going to be a second wave of results for the day (according to the release schedule, this should be all for today), but if this is everything for today, then Begich is in really good shape. Today was the day for the counting from the Mat-Su Valley (home turf for Sarah Palin and the state's most conservative core).
Today the state expects to count all absentee and questioned ballots left from the Matanuska-Susitna Borough and northern and western Alaska. Elections officials will also count most, if not all, Fairbanks ballots today. Tuesday is the ballot count for Anchorage and Southeast, where the majority of outstanding votes lie.
If Begich emerged from Mat-Su counting day with more rather than fewer votes, with areas like more Begich-friendly areas still on the table, then he's starting to look like he's in the clear. The question is starting to be whether he can get above the 0.5% threshold to avoid a state-paid recount.
UPDATE: It looks like a few more votes trickled in; at 11 pm Eastern, the lead is now 1,022 votes.
