Too early to tell. But I think it is important not to forget that his election (which I noted as a possibility before everyone else, heh) was essentially a freak event: every other candidate was, in some form or other, unpalatable to a majority of the electorate, and there stood he, the ultimate electoral blank cheque. For now, all we can say is that we don't even know who his biggest threat is likely to be, or from what direction they might come.
Don’t forget Covid will be a recent memory and indirectly an issue.
