I've only ever seen one time it was tried. The experiment was wildly successful: https://www.nationalreview.com/2014/01/voter-fraud-weve-got-...

Looks like those were in states that don't require ANY ID to vote, which I find ridiculous, so I guess we agree. I live in VA, we require ID, so the problem shown in NY shouldn't be possible.

And again, you still have to be willing to commit a felony to move the needly by ONE vote, which is not likely to be very common. The risk/reward simply isn't there.
