No! I don't think they have the right to vote. The fact that they are not paying their taxes, they are abolishing their obligations to their country, then why should they be given the right to vote? Afterall, they don't care about their country at all, so they shouldn't participate in political affairs as well. If they given up on their obligations to contribute to the upliftment of the country through their financial obligations, then they should give up all their rights.
