Tomorrow there is a general election in my home country Denmark.
Voter registration
There are different systems of voter registration around the world.
In some countries there are electoral roles being data silos of citizen master data more or less integrated with other citizen master data silos for other purposes as driving license administration, social security and taxation.
In Denmark we have an all-purpose single master data hub for citizens. When we have to vote, the ballots are extracted from the hub based on your age (from 18 on election day) and citizen status (excluding citizens of other countries living or working here).
The political scope
The voter’s role is to select members for the parliament. Then the parliament will select a prime minister.
One of the two most likely candidates for next prime minister is the current one with the nickname “Little Lars”, who came to power when the former one became general secretary of NATO and moved to the HQ in Brussels. Lars is head of the political party called Left (Venstre), which is a right wing party. He is going to defend the welfare state, including universal healthcare and free college.
His main opponent has the nickname “Gucci Helle”. She is leading the left block. She is going to defend the welfare state, including universal healthcare and free college.
Head of state
As voters we are not trusted to select the head of state. The queen was born to be queen, and her eldest son will be the next king. On the other hand, the members of the Royal Family are not allowed to vote in the election. This is the exception that confirms the rule.

It sounds like Denmark is well ahead of the UK here, although we’ve had a team of students tackling the problem over the summer. Check out the e-Voting project on the BBC and eightbar blog:

Thanks for the links James. Though communication between citizens and public sector is highly digitalized here in DK as described in the post The Trees Never Grow into Heaven, one area which is left on paper is the voting process, due to concerns about fraud, hacking and other security related issues.
