Mike,

The statistical text for significance is simple. The hypothesis to test would be:

The ballot has no bias. Voters for each candidate make the same double marking error proportional to their numbers (group population).

If it turns out that a large, disproportionate number of Democrats made this error but very few Republicans did then the hypothesis is false and the probability that the ballot has a built-in bias toward error becomes very probable depending on the degree of disparity between the voting groups' error counts.

Seeing the distribution of the error patterns in the 19,000(!) spoiled ballots would most probably immediately suggest the answer.
