I would wonder if some of the Dems might be reluctant to vote Aye/Nay, and just abstain to try and keep a low profile ?
Now that they (the Dems in office) have seen proof that even strongly and traditionally Democratic districts are willing to take action against anti-gun legislators,
and even go to great lengths to mount campaigns to get them successfully recalled, they MAY be afraid to "speak up" against such non-partisan legislation.

When voting to repeal,
one might NOT be surprised at the number of AYEs, but MIGHT BE surprised and the sparse number of Nays and numerous abstentions.
