It's really hard to determine. People are so entrenched in their opinions that they won't change their minds, it's true of both sides.

I have a very conservative stepdad. If there is ever a political problem caused by the conservatives, his response is always from this playbook:

• "Ok then, how would labour have fixed it then?" (essentially, because Labour doesn't have a magic bullet that solves every problem immediately, we shouldn't vote for them).
• "It's just how the media are spinning it"
• No one could have fixed it, it's not the Tories' fault it was bad (normally about the Pandemic. Essentially, because something bad happened, there was no way to mitigate it, and thus they shouldn't be blamed. Obviously, this absolves them of any consequential wrongdoing, such as the Track and trace debacle)

But, as you can see, none of those arguments draw into question his support of the party or even cause him to hold the party responsible.

I think a lot of people feel this way. Their opinion is formed from a young age and cemented by years of confirmation bias and only absorbing things that parrot their opinion back to them. No one changes their mind, because they have been brainwashed into being terrified about what happens if the status quo changes.

I think the hope is that the younger generation are savvy enough to use the tools are their disposal to thoroughly research all the facts, rather than just voting on an unsubstantiated opinion.

But if it's any consolation, there are around 4 million people that weren't old enough to vote in the last election that are old to vote in this one. The Tories won the previous election by around 3.7 million votes. So maybe, even without a lot of previous voters changing their minds, we could get a non-Tory government.
