With the EU elections in swing, if you think the likes of UKIP have a large share of nut cases, then you should have a look at "Direct Democracy Ireland" - basically a political wing of some Irish Freeman-of-the-land loons who get involved in the typical sovereign citizen type crap including that "debt is an illusion", that you can copyright your name and charge people to use it, different coloured paper and ink mean different things, believe that the courts system in the Irish Republic operates under "Admiralty Law" and that the bar stands for "British Accredited Registered", no statutory law has to be accepted (only what is written in the constitution) etc. etc.
Their ex-leader, Ben Gilroy, is standing as a party candidate. Recently he was up in court after breaching an order to stay away from a property that was in the process of being repossessed, acting as his own "lay barrister" - just before the judgement was delivered (4 week suspended sentence & pay court costs) Gilroy informed the judge over the case that he had petitioned the Oireachtas for him to be impeached and that he should in any case recuse himself!
Also on the campaign trail, Gilroy said that if elected to the EU Parliament he would align himself to UKIP. Farage very quickly distanced himself from DDI - says a lot when you're even too toxic for UKIP!
