<snip> Bush now leads Kerry by 52% to 45% among likely voters, compared with a 50% to 47% lead for Bush prior to the convention. <snip>
Bush received the same two-point "bounce" in his support among registered voters, from 47% before the convention to 49% afterward. Among this group, the candidates are essentially tied, with 49% saying they would vote for Bush and 48% for Kerry in the two-candidate race; and 48% for Bush, 46% for Kerry, and 4% for Nader in the three-candidate race. <snip>
Bush's bounce is the smallest an incumbent president has received. <snip>
Forty-nine percent of Americans gave Bush's speech a positive review, saying it was "excellent" (22%) or "good" (27%). That's just slightly worse than the 52% who rated Kerry's July acceptance speech in positive terms. <snip>
