The title says it all really. What would have happened in the 2016 American federal election if votes in the Electoral College were allocated proportionally, either within each state or nationwide? I was curious, so here's some number-crunching.

Electoral Votes Clinton Trump Johnson Stein McMullin
State-level Sainte-Laguë 263 261 12 1 1
State-level D'Hondt 267 266 3 1 1
National Sainte-Laguë 257 255 18 6 2
National D'Hondt 258 255 18 5 2
Weighted national Sainte-Laguë 257 253 19 6 3
Weighted national D'Hondt 258 255 18 5 2

Candidates other than those listed were not considered for the purposes of the calculation.

Here is my spreadsheet, if you'd like to look at the per-state breakdown. This was done very quickly, so please check my numbers! The Python code used is shown below:

NUM_CANDS = 5

while sum(evsAllocated) < evs:
maxquot = max(quotients)
maxcands = [i for i, j in enumerate(quotients) if j == maxquot]

if len(maxcands) > 1:
print('Error: A tie for the quotient.')
sys.exit(1)

evsAllocated[maxcands[0]] += 1
return evsAllocated

with open('data.tsv') as dataFile:
for line in dataFile:
data = line.rstrip('\n').split('\t')

assert len(data) == NUM_CANDS + 2

evs = int(data[1])
votes = [int(data[i + 2]) if len(data[i + 2]) > 0 else 0 for i in range(0, NUM_CANDS)]

result = getWinners(evs, votes, lambda v, s: v/(2*s+1)) + getWinners(evs, votes, lambda v, s: v/(s+1))

print(' '.join([str(x) for x in result]))


Input is of the form:

Alabama	9	718084	1306925	44211	9341
Alaska	3	93007	130415	15396	4699
Arizona	11	1123979	1219596	104688	32850
Arkansas	6	378632	681765	29662	9413	13187
etc.
