Churchill would never stand a chance of geting elected these days if this the cause of outrage. Funny how times change.
Churchill was only elected to lead the country by the population once , and in that case he did it despite having less votes , even if you add the partners votes to his he still got less votes than those he defeated in the election .
It was amazing that he got elected to power at all considering his landslide defeat when he stood the time before , and that at the time he did win he was really suffering visibly from his drink and health problems .

Anyhow as for the topic , McCain made a funny about bombing Iran .
He did it at a time when they are asking Iran to be really nice and do the world a really big favour , but are refusing to talk with them , yet make threats that both Iran and the US know are empty .
Maybe he thought it would go down well with the "base" .
It makes you wonder about his level of intelligence , and the intelligence of those that he is trying to appeal to .
