A four leaved clover is rarely seen and, hence, is considered a good luck symbol. It is believed that finding such a clover leaf brings lots of luck. The first leaflet is for faith, the second for hope, the third represents love, while the fourth one stands for luck. In Irish culture, the 3 leaved clover, also called "Shamrock", was used to represent the Holy Trinity, by Saint Patrick. One leaflet is for Father, one for Son and the third for the Holy Spirit. And when a Shamrock bears a fourth leaflet, it represents God's grace.
One of my friends (note - not a "client" or a "customer"; both phrases he despises!) is standing for election. I just want to wish him the best of luck; if anyone deserves to win and succeed in politics, it is him.
