> third parties merge to form coalitions that actually have a chance of winning. Rinse and repeat until you only have two parties. I would suggest that this probably isn't the case. Since there is no requirement for a majority vote share in first past the post, the same results can be achieved by splitting parties. The parties have more targeted appeal, just enough to squeak past the other parties. This is the case in India, for example. |

It is; both the theoretical and empirical support for this being the effect of FPTP is overwhelming.

Parties in FPTP will, to the extent that they can get away with it, funnel support to minor party candidates that will split the vote of their major opponent, but that’s a short-term tactical rather than long-term strategic maneuver.

It’s really not, though India is complicated by being a federal system (which means a bunch of different electoral area with different and interacting party systems) and being in the middle of a long realignment from, at the national level, a dominant-party system under Congress (and looks a lot like at least temporarily to a dominant party system under BJP, again at the national level.)
