Ryan had the better arguments, Biden bullied and postured. Biden won by firing up the target audience of discouraged Democrats, and by distracting the attention of the other target audience of low-information voters away from the Obama administration’s failures. (Distracting voters from his administration’s record is one of Obama’s main tactics.) Ryan was either too nice and too collegial as a matter of personal style, or perhaps tried too hard not to alienate undecided females who make voting decisions based on candidates’ demeanor. Biden was very rude, but it was clear from watching the subsequent interviews on Fox with a Luntz focus group of undecideds that many of these voters interpreted Biden’s crude domineering behavior as evidence of his skill and long experience. Whoever coached Biden to posture and interrupt knew what he was doing. The debate moderator, perhaps sensitive to pre-debate publicity about her friendship with Obama, made an effort to appear unbiased. Maybe it was a sincere effort. However, she asked Ryan more hard questions, tolerated Biden’s filibustering and his relentless tactical interruptions of Ryan, and allowed Biden to speak more overall. It may be that Obama gained no net support from this debate, but if he stopped Romney’s momentum for a while then he won a victory. The next few news cycles will be full of discussions about the debate rather than Obama’s failures.
