oknpv / share votes
To answer your question
"I never have had a good answer about who gets the proxy when shares are shorted. Could some one else get your vote because they "own" the same shares?"
There is only one vote per share.
In the case where someone, say person A, shorted shares, person A would have to deliver shares into the sale by borrowing the shares through the repo market. Say he borrowed the shares from person B. Person B, even though he owns the shares, would give up the right to vote these shares in the process of lending the shares to person A.
Person B could be someone who has purchased shares on margin or could be an institutional investor that lends shares for extra revenue.
In your question, you as the purchaser will have the vote and need not be concerned about where the shares came from or who gave up their vote.
