In the 2013 local elections he ran again and this time received approximately 20% of the votes, thereby securing a run-off against favourite Vladimír Maňka.

[24] Observers originally had said that they saw almost no chance for Kotleba to succeed in the second round against Maňka, but nonetheless found his strong showing "disturbing".

Despite elements of Neo-Nazism, the post-electoral polls suggest that his success was a result of dissatisfaction with the running of Slovakia and was seen as a protest vote against the ruling Smer – Sociálna demokracia and the fractured right.

[28] Kotleba was charged with demonstrating sympathy for a movement directed at suppression of fundamental rights and freedoms[29] by publicly donating €1,488 cheques to various families.
