This is a question about how effectively the public can endanger an MP's job at a General Election.
The Westminster system enables the public to campaign for or against any MP-candidate in any constituency.
So, for example you might live in a safe seat. But you can choose to campaign in marginal constituencies to bring the force of democracy for or against the Executive.
But in practise, how effective is this?
For example: recently someone mentioned to me how disliked Jeremy Hunt was when he was as Secretary of State for Health and Social Care. And yet he still won his constituency seat in the 2017 General Election. Given the widespread dislike of Jeremy Hunt, I might have expected people from all over the country to visit his constituency in South West Surrey to campaign against him and prevent his re-election. Was there such a campaign, and if so, why was it not successful?
And if there wasn't such a campaign, why?
