On the opening day of the Democratic National Convention, Democratic nominee Sen. John Kerry was in a dead-heat with his opponent, President Bush: 46 percent of those polled favored Bush and the same amount favored Kerry.

Today we found out, via Rasmussen, that Kerry's convention so far has netted him a one-point bounce in the polls. Through last night - a night after Kerry's acceptance speech - the Democratic candidate led Bush by a 47-46 margin.

The poll still allowed for some hope for the Kerry camp. Because Rasmussen compiles a three-day tracking number, only one-third of the voter interviews for this result happened after Kerry's speech to close the convention.
