Impeachment provides for this. At the federal level, you are bared from public office for life upon conviction. And it doesn't apply only to elected officials, but all public officials. Even some low person on the totem pole could be impeached, removed from their office, and bared from holding any public office ever again. Pardons do not apply to impeachment convictions. States vary in their impeachment proceedings and what burdens must be met.
