He probably has been emboldened by the political turmoil in the word over the last few years where voters have rejected establishment parties and politics to usher in a new dawn.
Not many saw Brexit happening and right up until the end no one gave Donald Trump a chance of becoming President of the United States. Both happened and turned traditional politics upside down in the process.
