Thanks HHI and Ohm. You helped clarify what I thought was straightforward in my first post. If you lend your shares (which can still be done with shares bought with cash in a margin account OR in a retirement account), you no longer can vote unless the broker messes something up. If someone borrows your shares, they vote, not you. If someone borrows your shares and shorts them, the buyer of those shares gets to vote, not the shorter and not you.

Ultimately whomever actually has physical (digital) possession of the shares can vote them. If you want to be sure you can vote, call your broker, recall your shares and make sure the broker has delivered them back to your account by 9/1, otherwise no vote.

Again, side benefit could be a bit of a short squeeze, more common in hard-to-borrow stocks where buy-ins occur if a broker can’t replace the recalled shares with shares from other lenders by T+2 (buyin occurs morning of T+3 - I’ve seen it happen several times).
