As we approach half-time in his presidency, just over half of Americans believe Barack Obama will not win re-election in 2012. Our final Reuters/Ipsos poll showed just one-third of those surveyed still thought President Obama would win a second term. An amazing transformation in the national mood in less than two years since the inauguration.

BRITAIN ECLIPSEA 60 Minutes/Vanity Fair poll found 39 percent of those surveyed believe Obama should be a one-term president, compared to 26 percent who wanted a second term and 33 percent who were unsure.

But as that oracle of election wisdom (my barber) observed to me today, for all the polls Obama’s chances in 2012 may come down to just one number. The jobless rate. Anything over 8 percent in 2012, and it will be a huge uphill battle for the president, Curtis predicted. Six percent and he stands a chance. Wise words indeed.

Finally today, and now that sanity (and/or fear) has been restored to these elections, we can end with some irony.

Our poll showed Obama scoring best for his performance on the war in Iraq, one achievement which arguably had more to do with his predecessor than him.
