(CNN) — Presumptive Democratic nominee Sen. John Kerry leads President Bush in the latest CNN/USA Today/Gallup poll, although the race appears to be fluid and remains close.
The poll, released Monday, found that among likely voters, ***Kerry was the choice of 52 percent*** and Bush 44 percent in a two-way matchup, with a margin of error of plus or minus 4 percentage points.
