A bill supported by Democrats to track children with vaccines has mercifully died in the state House. The cause of death has not been determined.

The AP reports that Democrats had enough support for it to pass the House, but not the Republican-controlled state Senate. It’s a curious excuse, and we don’t buy it. If Democrats backed down from every bill opposed by Senate Republicans, they would have very little work to do.

“The public health of Colorado was not enough to convince opponents of the bill,” said Rep. Dan Pabon, a Denver Democrat who proposed the database. “The politics around the ‘I word,’ or immunizations, just got to be too intense.”

We reported last month that Democrats supported shaming kids by including them in a database — a desperate measure to force parents to immunize their kids.

We suspect the bill failed because most Democrats didn’t want to be on the record for taking out their political frustrations on children.
