We are used to politicians claiming their shit smells of roses and that no other party can be trusted with the TV remote, never mind the economy.
That's the usual lies from politicians, whenever their lips move.
Carmichael is in deep trouble because he went far beyond the usual boundaries:
. He leaked to smear a specific politician leading a rival party. Then he lied about doing so and was found out.
So not a general smear about a party, but a personal one. Coincidentally, his intended victim had totally ouclassed and humiliated him in a debate during the Scottish Referendum. Just politics, or revenge too ?
. It was a lie. The French ambassador wouldn't lie to protect a UK regional politician (unless you live in tinfoil hat territory)
Carmichael might or might not have known at the time that it was untrue.
But even if you believe < eyes tinfoil > that Sturgeon wanted the Tories to win, it is a lie that she said so in that meeting.
. The French are miffed at being involved. Carmichael seriously crossed a line by embroiling foreign diplomats in UK party politics. He's put a civil servant in a stressful situation too.
. The smear was about something simple but dramatic, that the public can understand, rather than complicated (and boring to rUK) Scottish finance, legal or EU matters
. He wasted £1.4 million on an enquiry to find the leaker and then delayed the enquiry results until after the election.
. His own constituents are pissed off and trying to kick him out. They'll probably have their day in court and might succeed in forcing a by-election.
They might still vote for another Liberal candidate, but currently he is making the FibDem brand toxic in Scotland - so his colleagues may decide to turn on him.
. Worst of all, he may have contravened some laws, or at least skated around the edges: the police are currently investigating his actions Guardian
