But could the convention bounce evaporate like McCain’s?
Above is the latest Real Clear Politics round up of polling in the 2012 White House Race and the message is that the Obama gap has got wider and is being sustained.
Only Rasmussen is showing a different picture.
The big hope of the Romney camp must be that the boost that the President has received since the convention will, like with John McCain in 2008 be eroded rapidly more than a week out.
Also, of course, in the key swing states a different picture might be emerging. In Ohio, though, the gap has got wider.
That first Presidential debate on October 3rd is going to be crucial.
