Slay, ?slayed? and I'm done my homework

[FRITZ JUENGLING]

When I voted a few days ago, I noticed this odd phrase "... you vote this ballot..."  For me, it must be '..vote on this ballot'  What I saw would be acceptable only if one meant a round of voting--then I could say 'vote this ballot.'' Otherwise 'on.'

"He simply walked onstage and slayed his rivals...."

This is at least the third time this year that I've seen "slew"
replaced in print by "slayed." Language change in progress?  (I'm
ignoring "walked onstage" vs. "walked onto the stage.")
