No government should be in the business of murdering its citizens. Considering the costs of implementation and the alarming error rate, the death penalty should be abolished immediately.

The 2016 Democratic platform sums it up:

We will abolish the death penalty, which has proven to be a cruel and unusual form of punishment. It has no place in the United States of America. The application of the death penalty is arbitrary and unjust. The cost to taxpayers far exceeds those of life imprisonment. It does not deter crime. And, exonerations show a dangerous lack of reliability for what is an irreversible punishment.
