You are saying Putin's motive is to consolidate power. But he doesn't need to do this. He can walk the elections because he is very popular with the voters. In the last election he got 64% of the vote and the nearest candidate got 17%.
Are you under any medication at the moment? Nothing in May's claims about this affair make any sense unless it is a false flag op.or a mafia hit.
Why didn't they kill them when they were in Russia? They could have done it without any fuss.
They can and will do a lot to punish Russia. It is a PR disaster for Russia. Extra sanctions will seriously damage the Russian economy. The Americans and Israelis will get the green light from previously passive EU countries to step up their aggression in Syria and Eastern Europe. Do you see where this is heading? It is all about cui bono - who gains. Putin has nothing to gain from this but Israel and America now have an excuse to increase their predations.
He can get elected without doing anything like that. What you are saying just doesn't make sense. Have you heard about Occam's Razor. You get a really nice shave.
I'm afraid there is only one "useful idiot" here and I don't even think you are that useful.
