Turks living in Western countries voting en-masse for Erdo*an

The title already says it; why do Turks, living in Western countries, vote for erd*gan in such large amounts?

Is it because they like it that the Lira tanks hard, and can therefore spend more with their Euros that one time a year they actually visit Turkey on their summer holiday?

Truly baffling. Apart from that (but this goes for every country that allows it!) wild that a country allows people to have such influence on the political affairs of a country they don't spend at least half the days of each year in.
