> You typically only need a few thousand well placed votes to win an election, and even 100k impressions at $10 CPM is pretty inexpensive.

In the context of the EU this isn't true though, no political system in any EU member state relies on a tiny minority of votes from some states/provinces to completely tip an election.

There are still some discontinuities in the electoral systems where smallish number of votes can have a massive impact.

For example the run off thresholds in French legislative elections. And some places like Italy still use FPTP in a hybrid form.

However you're correct that there's nothing quite like Pennsylvania in the EU.
