After yesterday's primary results, lots of people are claiming it's over for Hillary Clinton. Drudge has even declared Obama to be "The Nominee". But Hillary hasn't quit yet. So, I've been wondering, is she just delusional, or does she still have a chance? I don't trust the media's analysis so I decided to try to figure it out for myself.
Assuming that the fine folks at Wikipedia have their numbers straight, here is the current delegate allocation:
A candidate needs 2024.5 delegate votes to win the nomination.
Hilary Clinton: 1,427.5 pledged delegates + 269.5 estimated superdelegates = 1,697 total delegates
Barak Obama: 1,589.5 pledged delegates + 255 estimated superdelegates = 1,844.5 total delegates
1697 + 1844.5 = 3541.5 delegates spoken for
4048 total delegate votes - 3541.5 = 506.5 delegates as yet unclaimed
Primaries remaining: West Virginia (28 pledged delegates), Kentucky (51), Oregon (52), Puerto Rico (55), Montana (16), South Dakota (15).
28 + 51 + 52 + 55 + 16 + 15 = 217 pledged delegates to be assigned via primaries
506.5 - 217 = 289.5 superdelegate votes as yet unclaimed
If the most recent polls are predictive of how the remaining states will vote, and if the delegate votes are being allocated proportionally (which they sort of are), here is how we can expect the candidates' delegate totals to change over the remaining of the primaries:
May 13: West Virginia: "The latest opinion polling shows Sen. Hillary Clinton holding a 56% to 27% lead over Sen. Barack Obama, with 17% undecided, as of May 4, 2008." If the undecideds vote proportionally to the decideds, the final vote should be 67% Clinton, 33% Obama. So, +19 delegates for Clinton, bringing her total to 1716, +9 delegates for Obama, bringing his total to 1853.5.
May 20: Kentucky: "According to a recent poll from Survey USA conducted from April 26-28, Clinton leads Obama 56% to 31% in Kentucky with 13% undecided." If the undecideds vote proportionally, the final vote should be 64% Clinton, 36% Obama. So, +33 delegates for Clinton, bringing her total to 1749, +18 delegates for Obama, bringing his total to 1871.5.
May 20: Oregon: SurveyUSA's April 28–April 30, 2008 poll has Clinton 44% Obama 50% Other 2% Undecided 4%. If the undecideds and "other" are ultimately divided proportionally, the final vote should be 47% Clinton, 53% Obama. So, +24 delegates for Clinton, bringing her total to 1773, +28 delegates for Obama, bringing his total to 1899.5.
June 1: Puerto Rico: "In a poll conducted from March 31-April 5, 2008, Clinton leads Obama by 13%, holding 50% to his 37%, with 13% undecided and a margin of error of ± 4.4%." If the undecideds vote proportionally, the final vote should be 57% Clinton, 43% Obama. So, +32 delegates for Clinton, bringing her total to 1805, +23 delegates for Obama, bringing his total to 1922.5.
June 3: Montana: Unfortunately, it appears that the most recent poll was taken back in December 17-December 19, 2007, with "Clinton 29%, Edwards 19%, Obama 17%". If the votes are split proportional to how Clinton and Obama were doing then, the final vote should be 63% Clinton, 37% Obama. So, +10 delegates for Clinton, bringing her total to 1815, +6 delegates for Obama, bringing his total to 1928.5.
June 3: South Dakota: A poll dated April 3, 2008 has Obama 46%, Clinton 34%, Undecided 10%, No One 6%, Other 4%. If the votes are split proportionally, the final vote should be 42% Clinton, 58% Obama. So, +6 delegates for Clinton, brining her total to 1821, +9 delegates for Obama, bringing his total to 1937.5.
No more primaries. Clinton will now have 45% of the 4048 delegate votes and Obama will have 48%. That doesn't seem like a huge difference.
1821 + 1937.5 = 3758.5 delegates are now spoken for.
4048 - 3758.5 = 289.5 unclaimed delegates remain (the unclaimed superdelegates I also calculated above).
Clinton will need 2024.5 - 1821 = 203.5 of the remaining 289.5 superdelegates to win, or 70%.
Obama will need 2024.5 - 1937.5 = 87 of the remaining 295.5 superdelegates to win, or 30%.
Hmm, it seems unlikely that she can do that.
However, these calculations make some important assumptions that might very well not be true:
- The latest polls accurately predict how people will vote in the primaries
- The pledged delegates will be allocated proportional to the primary vote percentages (they are actually allocated by district, so it's possible to lose the state primary but win more delegates)
- The undecided/"other" voters will be divided proportionally based on how the candidates are currently polling
- No currently spoken-for superdelegates change their minds
- Michigan and Florida will not be counted
All of those assumptions could easily be wrong enough to significantly affect the outcome (at least one almost certainly is, although I don't know which one(s)).
So, unfortunately (I am not a Hillary fan), I think although it currently seems unlikely that she will win, it is not yet impossible. She is ahead in the polls for most of the remaining states' primaries and who knows what those superdelegates will do? Plus, if they decide to seat Michigan and Florida after all or have a do-over, Clinton won both those states (Obama wasn't on the ballot in Michigan) and that could tip the balance in her favor even if their delegates only count for half.
If I were Hillary Clinton, I wouldn't quit now either. I think it's going all the way to the convention.
