Another way of saying that, stop me if this is wrong, but one way to say that is we've been assuming that politics is one dimensional, left/right and there might be other things involved: character or even among issues, even among political issues it could be more than one dimension.

换句话说就是,如果我说错了请纠正,换种说法就是,我们把政治假定为单一维度的,非左即右,然而它还涉及其他方面,比如性格问题,即使政治事务的处理也不是单一维度的
