You fool, you can't prove a negative! You alleged it, so you come up with the evidence. Why would they? Just because you wouldn't vote for someone like that doesn't mean they would punish him just on that. That is bull and you know it. For one thing, many people do not vote. For another not everyone votes for the government. Even then as I said there are many issues at the ballot box. I have never heard of a situation where someone has been voted out simply because he went to a shrine (or similar). If you are so sure support for Koizumi/Abe was/is based on glorifying the war/war criminals you should be able to find a Japanese newspaper article saying something along those lines.
