WASHINGTON (AP) _ George W. Bush is widening his lead over Al Gore in polling among likely voters a little more than four months before the presidential election, new surveys suggest.

Bush was chosen by 52 percent of voters and Gore by 39 percent in a weekend telephone survey, according to a CNN-USA Today-Gallup poll released Monday.

The same poll taken the week of June 5 showed Bush, the Republican Texas governor, with 48 percent and Gore, the Democratic vice president, with 44 percent with the same margin of error of plus or minus 5 percentage points. It was 49-42 for Bush in the same poll late last month.

A Voter.com-Battleground poll last week had it 52-40 for Bush, up from a 6-point margin in May.
