It's that they want instant gratification.... They go into McDonald's and order a Big Mac .. a few minutes later they get what they want.

They vote for one team... They want everything that they wished for .... When they don't get it even if it wasn't 'promised' ... They are unhappy.

They imagine the other team... Well they would have granted our dreams... Like a political genie

Nobody saves for anything and politicians don't give time scales ... Plus people want 'it' now

Possibly. I wouldn't say everyone who votes that way eats at McDonalds though.

It's like people have short memories or they are just not politically engaged enough.

So when things go shit, their only response is: Vote for the other team.

And when things stay shit, they go: Can we have the previous team back again?

Although I suppose the Tory lead is down to a large number of people losing interest in all of them.

I don't think lots of people switch in massive numbers... It's a case of not getting what you want so you don't vote... Tory vote plummeted, but Labour didn't pick up that number

Harris vote was poor with Democrats not voting, but Trump didn't increase his percentage

Complex issue but politicians are not engaging their target audience

When people don't get or hear what they want they seem to switch off
