Looks like I have to take it all back! It appears that it was Tony Evers' original budget proposal that requested the change in language to impose the hybrid fee on all (including gas-only) hybrids. Don't know who was advising him, but it is truly a big disappointment. I actually wrote the gov and asked him to veto what looks like his own proposal. Ha!
