The fact that people use the most recent history to judge politicians is easily established by election results tending to align closely with what credible pre-election polls show. And people can see for themselves how polls tend to swing in response to what voters view as "benchmark"/important current events or the like. Whether you like this or not is irrelevant.
Further, I didn't say that long term plans are irrelevant but it's easily understood why few would focus more on it as opposed to recent performance, particularly in respect of an incumbent government. Many of the same people will (if re-elected) still be around and this has a lot more bearing than what they think they can/will do in 4 or 5 years' time, when some of these people won't be around.
Is that really too hard for you to understand?
No, its not too hard for me to understand. I dont recall saying that long term plans are the be all and end all, nor that short term events are not important. In my opinion, I feel that enough take a view of longer term goals as part of their vote to make that material, you feel its less so, and thats fine
