In this day and age (the information age, specifically) the electoral college is no longer needed to fulfill its original purpose. Bring on the tyranny of the majority! . . . and that's all I have to say about that.
As far testing goes, it's a good idea, but I can already see what will happen. It'll start out with good intentions, but then gradually bloat (not unlike other testing systems that we all know and love). Soon enough, there would be USPLE steps I-XII (I think most Presidents - at least the current one - have or should have been in a twelve step program, so maybe it's not such a big deterrent). USPLE step II, WS (waffling skills - an additional test to the written or "knowledge" portion) will be contested in the courts as being too expensive and redundant. Step VII, IM (intern management - another practical test) will prompt predictable outcry and calls of partisan politics, not to mention potential harassment of the calibrated interns. Fairly soon, the process will be so cumbersome and expensive, that only the elite who come from money will be able to apply for the Presidency . . . wait a minute...
