DMK: As the sun rises to dispel the darkness, our sons (and daughters too) shall rise to take up our positions when we are physically no longer up to the task.
MDMK (Marumalarchi DMK): We shall maintain our balance & try to stay in power in the midst of changing alliances & electoral verdicts. Like a spinning top.
PMK (Pattali Makkal Katchi): The fruits of power are sweet & nothing is sweeter than the king of fruits. Whatever be the duration of our rule, we shall maximise our earnings during that period.
Samajwadi Party: We strive to make the lives of common man more comfortable. We shall promote the use of bicycles as a favoured means of transport for reasons of health & environment. The funds allocated for the road sector shall be used to fill the potholes on the roads (and our own bank accounts).
Trinamool Congress: Those who call this flower "fool" are all either naxalites, maoists or communists.
For an international flavour, here are the logos of the major parties in the most advanced democracy (USA):
Democratic Party: I am an ass
Republican Party: I have a bigger ass
