In a time of crisis when we need calm heads and a steady nerve, it makes me fearful that McCain can't control his own party, let alone a Super Power. Mc Cain/ Palin have unleashed a truly ugly side of the US character, doing a great country a huge disservice. He should be ashamed of himself.

Bruce Robinson, Plymouth, UK

It is quite bewildering and most concerning that in the 21st century America some people feel so insecure about a man's colour and name. If Obama was white and was named John instead, Americans will be seeing him as the great messiah and political saviour and genius.

I suppose none of you have considered that this massive sell-off of stocks is due to fear that the socialist Obama might actually be elected.

Its morning again in America - only positivity should win this election. I fully support Obama's position and I only hope it triumphs over McCain's last gasp efforts

"I think the rest of us in the world should leave the Americans to their destiny.

tolu, Lagos, Africa, "

Thing is, are Americans capable of leaving the rest of the world alone?

If the financial crisis makes that possible, then I welcome it.

Bilal Patel, London, UK

It's disgusting that McCain isn't honourable enough to denounce the hecklers in his and Palin's supporters who hurl insults at Obama. This is not the way to conduct an election. The Republicans are fighting a disreputable campaign.

Bob, London,

A calm intelligent black man in the White House will be exceedingly good for international relations and may heal some of the Republican damages that have been done in the past 30 years. We can only pray that Americans will choose him instead of another fear mongering hot head.

Tom, is America not for Americans don't the people deserve the leader they get. I think the rest of us in the world should leave the Americans to their destiny. We can't love America more than Americans or can we?

."..as a voter asked Mr McCain about his rival, the crowd erupted in calling names, with one women shouting "Obama Osama!"

What a great advertisement for the intelligence of the US electorate.

McCain: "Rather than answer his critics, Senator Obama will try to distract you from noticing that he never answers the serious and legitimate questions he has been asked."

Bit rich, given that his running mate answers every question by telling us what 'soccer moms' and 'Joe Six Pack' think

Sophie, Birmingham,

The stock market reflects the confidence people have in either candidate for President of the US, a flawed electoral system in the US, now allows such unlikely characters to attain such status. I respect McCain for his history but Obama has an odd background for such high office. Not my vote.

Payne, Honolulu,

Unfortunately Gabriel, I am very worried that the American people will focus on the fear and insecurity being served-up by the McCain campaign. Just look at the previous two American elections. Another republican administration would be a disaster not only for America, but for the entire world.

Tom K., Chicago, USA

What I do not understand about Obama the Magnificent is why he is not doing anything about the financial mess. He told us that he " would lower the seas, heal the sick and heal the planet ". He should not break in to sweat over a little thing like a money problem. Maybe someone could ask him .

Desmond Taylor, Houston, USA,TX

The latest McCain ads brand Obama "too risky". There's only one guy who's too risky for America right now and it's the old guy flailing around in the midst of an economic crisis, making policies up as he goes along and turning a blind eye as his campaign crowds get ever more extreme.

MussieCraig, Musselburgh, Scotland

The Republicans are masters at spreading fear and insecurity, Bush was very successful and McCain is going to continue this shameful trend, i just hope that the American people dont rise upto this disgraceful behaviour.

Gabriel, Dublin, Ireland

McCain is lowering his campaign to the lowest common demonator. He should be very ashamed of himself. I hope he has many, many sleepless nights thinking about the hate he is spewing.

Susan Wellmann, Halifax, Canada

Why should Americans worry about their economy, McCain says it is very strong. There is no one having their homes foreclosed. There is no one losing their jobs! There is no factory being closed down in America. American people have nothing to worry about, things are just fine.

Daphne Kenward, Cambridge, UK

Any character or intregrity that Mr. Mc Cain had come into the campaign with has desolved into a hateful, divisive tirade like that of a spoiled child who has been told he is going to lose something he has always dreamed of having.
