If you genuinely think any of them ( any MP any party ) could do better under the current conditions , your as crazy as they are . No one has ever been in this position before , so how exactly do you deal with it ? . The only thing you can be sure of , is that the other fella will always tell you he would do it better .
Besides , Boris takes he`s lead from his advisors , and most of those don`t agree all the time , so exactly who is at fault , the leader for taking his advisor`s advice , or the advisor`s for giving the advice ? .
To certain extent I agree with you, the pandemic response is a very fine balancing act and would be difficult for anyone.
But off the top of my head, I can't imagine the other parties would enabled their advisors to stay in a job and defended them after publicly flouting the rules, or granted huge contracts to people with no expertise, or been so indecisive so many times, or failed to recognise that the pandemic response should be the priority now, not fish, or used racist and zenophobic rhetoric, or tried to subvert parliament to achieve their goals, or appointed Russian oligarchs to the house of Lords, etc. etc. etc.
