Fouad Makhzoumi went with "thanks to you, now it is our right to believe what can achieve" (rhymes in Arabic).
The Lebanese Forces smartly played it with their own "sar badda" (now is the time) which placed in a different context becomes "when the time came you proved worthy, we thank you".
And then we have Nicolas Sehnaoui who again referenced his earlier slogan "for Beirut to become first" (since he is running in the first district) and his line is "the first thanks is to you".
See? It costs nothing to be polite!
