On one level you could say that popularity amongst voters is the only metric that matters for a politician, but I agree there are other ways of evaluating a politician. I’d argue that Nick Clegg is a poor politician because he was outmanoeuvred by David Cameron (the PM to Clegg’s Deputy PM). The best example is the AV vote on introducing proportional representation, where Clegg was setup with a poor alternative that would be hard to sell, and the campaign was savaged by the Tories and their media allies from the start. And there are many other such examples.
