I don't agree with what Philip Hammond did as Chancellor (most of the time). HOWEVER, if I were one of his Conservative-voting constituents, I think I'd be pretty miffed about some upstart coming along and trying to kick out the man I'd voted for for years. His constituency was marginally Remain.
I think in a General Election, I'd vote for Hammond as an Independent instead of an official Conservative candidate, most of whom seem to have been cloned.
The Conservatives are ahead in the polls. However, I wonder what difference it would make with another Labour leader (Starmer perhaps?) and how some of the seats with Independents will vote.
There is a very real prospect that the Conservatives would lose South Cambridgeshire, despite its history as a Tory stronghold. It voted 60.2% Remain, now has a LibDem council and shows as one of the areas with the highest percentage of constituents signing the "do not prorogue Parliament" petition. Companies have already lost contracts and funding as a result of Brexit. If Heidi Allen stands as LibDem, there's a realistic chance she'll win.
