AK-Sen: Absentees (and Provisionals) May Hurt Murkowski

I haven't been up with SSP as much as I would have liked to be over the past few days, but the brewing brouhaha in Alaska was too good for me to pass up.

First, let's take a quick look at the geography of the vote, by state house district (blue for Murkowski, red for Miller):


Murkowski did well in the southeastern part of the state, as well as the Arctic North, and the Aleutians. In the Anchorage-area inset below, you can also see that she did well in the Dem-leaning (and less GOP-vote heavy) Anchorage-city districts, but got absolutely crushed in the GOP-vote-rich Mat-Su Valley north of the city (no surprise, given Palin's involvement).

For the analysis and maps presented here, I use Alaska House of Representative Districts, numbering 40 in total. I also rely extensively on 2008 absentee and provisional ballot rates, which I think is a reliable assumption; Election Day only turnout between the two contests is remarkably similar:

I'd also hoped to use Young v. Parnell in 2008 as a proxy for Murkowski and Miller respectively, but the correlation there isn't as strong:

Between the 40 House Districts, there was a huge variation in the percentage of GOP ballots that were cast absentee in 2008, ranging from 2.96% in HD-39 (Nome), to 20.47% in the Anchorage-based HD-18.

Using this analysis, the outcome already begins to look grim for Lisa Murkowski. Here is a comparison of her Election Day performance and the percentage of votes cast absentee in 2008:

From this, I think we can expect fewer absentee ballots from her stronger areas, and more absentee ballots from areas more favorable to Miller.

Things look even worse for her when we start to factor in the fact that there is variation in the number of votes cast per HD, and therefore variation in the number of absentee ballots returned per HD. In 2008, this varied from a tiny 28 absentees in HD-39, to 741 in HD-34 (Rural Kenai). Assuming that each HD returns the same percentage of total absentees as they did in 2008, this is what we get:

That negative correlation we saw earlier becomes even stronger, as Miller strongholds are expected to return more of the absentee ballots outstanding. Adding the additional assumption of Murkowski's performance among absentees to be the same as her Election Day performance (tenuous, yes), she can be expected to receive about 48.51% of the absentee vote.

Repeating this analysis for provisional ballots, things are no better for Lisa.


While the relationship between her Election Day performance and provisional ballot rate seems to be better, adding into consideration the percentage of statewide provisionals per HD shows that familiar negative correlation for her. Making the same assumptions as above, Murkowski can be expected to get 48.82% of the provisional vote.

Extrapolating further, using the oft-cited 7,500 absentees and assuming 5,000 provisionals (5,200 were cast in 2008), we can expect Miller's margin to increase by 223 votes among absentees and 118 votes among provisionals. For Murkowski to pull this out assuming those figures for outstanding ballots, Murkowski would have to perform 8.04% better than she did on Election Day among absentees and provisionals...which is quite the tall order! More outstanding ballots means the swing she needs will be less, but it also means more ballots through which she could lose more ground. Given this, there isn't too much reason to be optimistic for Lisa, and we might just have to put the 'W' in the column for the Grizzly Momma.

Estimated Murkowski percentage is obtained by taking the weighted average of her performance by HD, with weights being the percentage of statewide absentees/provisionals cast within the HD.

Nice!
Thanks for the analysis jeffmd.  I think it is interesting.  I agree that Lisa looks unlikely to pull this one out.  However, does anyone think that Murkowski has a shot at a better percentage among absentee ballots than among election day ballots?  I am assuming that Miller closed late.  Some of the absentees may have been cast even before the third party advertising blitz for Miller.

I love the work
But this race is over.

What I really want to see is your model for predicting all Congressional winners for every district, Senate winners for each state and the exact congressional maps for each state after 2010-2 redistricting.

When will this be done?  

LOL


And the lottery numbers.

How bout this...
Where will McAdams have to win, compared to Begich's win in 2008? I've tried to find the area Mark won in 2008 so I can see for myself, but I haven't been able to find them. Maybe you have somewhere you can find them.

Begich is Red, Stevens is Blue

Same coalition.
  McAdams needs the same coalition.  Maybe he can pick up the Ketchikan area in the southeast which rather oddly supported Stevens.

24, Male, GA-05

Same coalition
Not odd at all.  Ketchikan, if you recall, would have been the beneficiary of the Gravina Island Bridge if Stevens had his way.  You have to be a fanatical idealist to turn against someone who tried to get $400 million in government investment into your 7,000 person community.

McAdams
McAdams has got no chance here, even if Murkowski decides to run as a Libertarian.  I've lived and voted in Alaska since 1980 and a Democrat has to have years of name recognition in Anchorage to have a shot at a national or statewide office.  

Probably the only way for the Democrats to pick up this seat is if McAdams drops out and the ADP chooses Tony Knowles to replace him on the ballot.

Good stuff!
Great work on this. Really interesting. Cant wait to see how your numbers compare to the final count.

I'm betting that
Murkowski does better than this 48% here, but not enough to put her into the lead.

party: Democratic, ideology: moderate, district: CT-01

Absentees will favor her
by a lot, compared to all parallel results on election day.  The longer ago a person voted, the more likely Murkowski got the vote.  I'm sure she is counting on that, but she has to get a 4000-2000 kind of break to win.  

[ Parent ]
The thing is, though, how aware were people of Miller
when they bothered to request their absentee ballot?

party: Democratic, ideology: moderate, district: CT-01

[ Parent ]
Exactly
That factor particularly favors her.  Nobody says, "Oh, I may want to vote for Some Dude by absentee."

Absentees should heavily favor Murkowski, regardless of where the voters are from.  The thing to consider is where those people's brains were when the bulk of them voted.
