Generally speaking, the idea of political parties blending forces, making deals with one another during elections, is not a sound one. Political parties have identities, and those identities emerge from their policies and history — and from their differences with other parties.A deal nullifies their essential being, discards for mere advantage what makes them who and what they are. (It's like, say, a Baptist, choosing to be a Catholic for a day, or — let's get really religious — an Apple user deciding to tout Bill Gates.)
