Instant-reaction polls following Monday night’s debate in Boca Raton, Fla., judged President Obama to be the winner. …
The first presidential debate produced roughly a 4-point bounce in head-to-head polls toward Mr. Romney, while the second presidential debate brought no appreciable bounce toward Mr. Obama.
It is tempting to split the difference, and assume that Mr. Obama might get a 1- or 2-point bounce in the polls, but there are some mitigating factors. [cont.]
