OP - I voted Conservative this week but was mightily tempted to vote for Reform. I will likely vote for them in the next GE.
I am an ex card carrying Labour member and voter. I did not vote for them in the last GE and spoilt my ballot.
The writing was on the wall that Labour would be abysmal and anyone who thought otherwise wasn't paying attention imo. It was evident a long time before the GE who Starmer and his allies are (see "The Labour Files" investigation).
My immediate family voted Reform this week, some of whom are mixed race, some like myself, are immigrants to the UK. All of us are tired of being told we are racist for having legitimate concerns about immigration levels and the cost to taxpayers. We are tired of being labelled far right racists. I am currently between jobs and cannot claim a cent to help me in any small way, yet, down the road from my house are two hotels housing hundreds of male asylum seekers getting food, housing, etc etc etc. My neighbour has been evicted from her private rental (landlord is selling) with her two toddlers and she is still waiting for proper housing - this comes after the Labour Council removed THOUSANDS of local residents from the housing list, including her.
This town is creaking under the decisions the Labour led Council and successive governments have taken over the last 20 years. Getting a GP appointment is nearly impossible, our roads are a fucking mess, the Council wants to pedestrianise the high street against the wishes of the businesses operating on it, there are tons of dodgy Turkish barbers, the town centre is rapidly declining in favour of high rise flats to appeal to Londoners, spunking money to graffiti cycle track underpasses because there is nothing else that money could be used for, a shockingly bad train service made worse by govt. decision to allow a state own and operated train company to cut stops impacting commuters to London, locals teaming up to do litter picking and tidying up of public areas because the Council doesn't do it, extortionate parking fees set by the Council in car parks, their obsession with net zero impacting town design and parking decisions (we have thousands of new houses and flats being built in the countryside around and in the town, many with no parking because "reasons"), poor to no maintenence of an extensive cycle track network. I could go on and on about local issues before I even start on the policies this government has taken since coming into power.
I can completely understand why people are sick of the status quo (Conservatives and Labour) and are willing to take a bet on something radically different, be it Reform or Green (who are batshit imo). People are frustrated and have had enough. IMO, this week was a 'fuck you' to Labour and voters, including those that voted for Labour, telling the government you are on the wrong track and need to course correct, fast.
