His total vote was 255,809
Her total vote was 155,686
overall total was 411,495
12% of the total (49,379) was (R)epublican crossover
Split 25% (15,344) Obama and 75% (34,034) Clinton
34,034 is 24% of Clinton's total vote of 155,686
15,345 is 6% of Obama's total vote of 255,809
Deducting these numbers we have
Total w/o Republicans
Obama 240,809 (67%)
Clinton 118,321 (32.9)
Overall total 359,230
I suspect that if we went further we'd find that the big supposed losses for Obama among whites is a product of this crossover republican vote.
Added on edit:
There are two crossover groups voting for two different reasons.
There are the disaffected (R) that have been crossing over since the beginning.
There are also the gremlins crossing over at the behest of Limbaugh in order to vote for hillary.
I don't think the second group is voted for Barack, but it's possible.
Discounting that possibility for the moment, the logic is that the 25% that voted for Obama in MS (nowhere else did limbaugh have as much lead time to urge the crossover) are real crossovers because we should assume that Limbaugh's listeners wouldn't have voted for Hillary.
What we don't know is the number of Hill's voters that were Limbaugh inspired and the number that were genuine crossover.
So I chose to just remove the tallies from both columns.
I haven't seen the totals but it would be interesting to see a breakdown by primary with the closed primaries used as controls.
