Mitt Romney's selection of Paul Ryan of Wisconsin as his running mate has not altered the race against the US president, Barack Obama, despite receiving huge media attention. The campaign remains neck and neck with less than three months to go, an AP-GfK poll reveals.
Overall, 47% of registered voters said they planned to back Obama and the vice-president, Joe Biden, in November, while 46% favoured Romney and Ryan. In a June AP-GfK survey the split was 47% for the president to 44% for Romney.
At the same time, there was a far wider gap when people were asked who they thought would win. Some 58% of adults said they expected Obama to be re-elected, while just 32% said they thought he'd be voted out of office.
