McCain gains one and Obama loses one for a net two point gain for the Arizona senator and his new running mate.
Another significant mark for McCain…this is the first time he has hit 49%. Previously his high was 48%.
More from Gallup about historical bounces:
That is slightly better than Barack Obama’s four-point bounce from 45% in Aug. 22-24 polling before the Democratic National Convention started to 49% immediately after it concluded. Since 1964, the typical convention bounce has been five percentage points.
And here’s a chart of the bounces of each party’s nominee since 1964. All of the eventual winners are highlighted, but I’ve put the winners who had a bigger bounce than their opponent in red and the ones who had a smaller one in blue.
So, will the bounce continue tomorrow?
