So technically your math is slightly off, sorry.

Interesting to see candidates are on the ballot by different names in different states, though I guess it sort of makes sense.

As for the name thing, it won't surprise you that I'm very much not a fan of women taking their husbands' names, especially when it's a legal name change and not merely a social one. Keeping their fathers' names puts them in precisely the same position as men, which after all is the general idea, so your side comment on that really makes no sense. But obviously in her case the benefits of using 'Clinton' would outweigh the price.
