Denver voters Tuesday soundly defeated a ballot initiative that would have significantly restricted police discretion on whether to impound cars driven by unlicensed drivers.

Initiative 300 had prompted opposition from an array of civic and political leaders. They told voters the initiative would unnecessarily tie up police resources and become a costly bureaucratic burden. Opponents also said it was a thinly veiled attack against illegal immigrants.

The measure was rejected by nearly seven of every 10 voters.
