Debate Scores: McCain Improves but Obama Takes the Prize
McCain improved his debate image, but not enough to knock down Obama.
Oct. 18, 2008 — -- John McCain improved his debate scores in his final encounter with Barack Obama, but not enough to challenge Obama's dominance across their three meetings -- an advantage that's improved Obama's image well beyond his core supporters.
Likely voters by 3-1 say they have a better rather than worse opinion of Obama because of his debate performances. It's helped him in key groups including white voters overall, working-class whites, independents, married women, white Catholics -- even among conservatives and perhaps evangelical white Protestants, core Republican constituencies.
Overall, 36 percent of likely voters in this ABC News/Washington Post poll say they have a better opinion of Obama as a result of the debates, 12 percent worse. That compares with McCain's result: Just 20 percent think better of him, vs. 26 percent worse.
Nonetheless, that's a good deal less negative than it was for McCain after the second debate, when just 12 percent thought better of him, 28 percent worse. The last debate did help McCain's overall score -- but not enough to rival Obama's.
Debates rarely have a measurable, direct impact on vote preferences, and Obama's overall advance against McCain came before the debates began, fueled by the global economic crisis.
Nonetheless debates can more subtly influence campaign dynamics, either by reassuring voters or raising doubts. And the number of voters who say the debates had no impact on their thinking declined sharply from two-thirds after the first debate to barely over half now.
GROUPS – The advantage is Obama's not just overall but among important groups. Independents, for example -- classic swing voters -- by 33 percent to 13 percent say the debates made them think better rather than worse of Obama. For McCain, by contrast, the assessment among independents is 19 percent better, 28 percent worse.
Obama's also seen more favorably rather than less so by white Catholics, 26 percent to 13 percent, and by married women, 35 percent to 14 percent, two more swing voter groups. McCain's debate rating is about the same among white Catholics, but weaker among married women.
