Providing that they don't stuff the balot box you mean...
What @Lord Sovereign
says is true. The Netherlands, like all
other non-Third-World countries except
the USA, demands voter ID. After a brief experiment, voting machines have also been rejected, because they're just not trustworthy enough. Ballots only.
Last general election, some silly goose of a left-wing girl who volunteered at one of the polling stations tweeted a joke that she might "lose" a few right-wing votes. This was a national outrage for several days, resulted in her being removed immediately (and then detained and questioned by the police), and promptly caused immediate security measures to be taken during that election.
The Dutch establishment doesn't have to stuff the ballot box. They're pretty secure in the knowledge that, if all else fails, they can still form... like... a seven-party establishment coalition that exists purely to keep the populists out of power. And it would change nothing for any of them, because they don't have principles anyway. The supposed business party can easily govern with the socialists: neither have any
ideals other than "power for ME".
Also, why did the USA stop using that system in 1913? (I'm going to guess that bastard Woodrow Wilson was involved somehow...)
The seventeenth amendment is one thing we can't actually blame on that bastard Wilson. It was passed by Congress in 1912, before he was elected, and was only ratified by the states in 1913. The only Wilson I can tie to this is James
Wilson... the only Founding Father who wanted Senators elected directly. (In fact, most elements of "mass democracy" that are in the USA's political system were put there at James Wilson's urging. It's very interesting that his influence -- for good or ill -- is so often overlooked. But I'm veering off topic...)
