Polls suggest Mr Wilders’s popularity is waning, while Mr Roemer is the rising star.
“I’ve never seen anything like this. It’s totally splintering,” says Ron Meerhof, a seasoned political journalist at the popular Volkskrant newspaper.
“Voters are going all over the place, they’re very volatile. They feel like the big parties don’t have the answers. It’s interesting and impossible to predict what will happen.”
At a Freedom Party rally in Rotterdam there was a conspicuous number of empty chairs.
I asked Mr Wilders if he would be willing to join forces with Mr Roemer to form a government.
“I have not excluded anyone,” he said.
And he made clear the party’s anti-Islamic platform was no longer its main campaign theme.
“I believe Europe is the only subject that matters in these elections. We don’t want to be a slave of Brussels – we want to be an independent country and this is the choice we are offering the electorate.”
Emile Roemer appears to be an attractive prospect for the disenchanted masses – a smiling, self-assured, open-collar-and-no-tie man.
In the popularity stakes, he comes in just behind the nation’s favourite Queen Beatrix.
