This was quite a battle in Utah last year. At one point, the opponents of the measure pointed out that a driver over the age of 65 is naturally more 'impaired' than a younger person at .05 BAC. The governor, who is 70, was not amused.
He must have got a lot of push back from the tourism industry though, because he has been walking this back, talking about a tiered penalty system and having the legislature revisit the measure.
