Tomorrow is Polling Day. Who will get my vote does not depend on the political party that he belongs to. Ultimately, the deciding factor for me is whether the MP genuinely cares for his constituents. If he only appears to be 'active' in his constituency just before election but he is not present during Meet-the-People sessions, then I can't say that he really has a heart for the people that he is supposed to serve.
Do to others what you want others to do to you.
