In a poll of 962 British adults interviewed 29-31 October 2004, asked "If you had a vote in the American Presidential election to be held on Tuesday, would you vote for the Republican candidate, George W. Bush, the Democratic candidate John Kerry, a third candidate, Ralph Nader, or some other candidate?"
Bush 21% Kerry 45% Nader 2% Other 6% Would not vote 13% Kon't know 13%
Kerry lead over Bush 24%
A second question asked:
"How important is it to you personally who wins the American Presidential election?"
Very important 25% Fairly immportant 30% Not very important 25% Not at all imp't 19% Don't know 1%
this compares to the 2001 British General Election:
Very 32% Fairly 34% Not Very 25% Not at all 8% DK 1%
So 55% Very/Fairly for US compares to 66% for their own country.
