WASHINGTON (AP) _ George W. Bush and Al Gore have big leads in their parties' presidential nomination races, according to a Time-CNN poll out Friday.

The poll also indicated people have more faith in the Democratic Party _ by a 40 percent-to-28 percent margin _ to do a better job of handling the nation's problems.

The pro-Democratic tilt on issues has showed up in several polls in the last week. But Rep. Christopher Cox, a California Republican, told CNN that the poll results on who people trust on issues ``are all over the map'' depending on how the question is asked.

According to the poll, Bush, the governor of Texas, had roughly a 10-point lead over either Gore or Bill Bradley in a head-to-head matchup with the two Democrats.

In the Republican race, Bush had a 59 percent-to-13 percent lead over Arizona Sen. John McCain. Publisher Steve Forbes followed with 7 percent, activist Gary Bauer with 4 percent, Utah Sen. Orrin Hatch with 3 percent and commentator Alan Keyes with 2 percent.

Vice President Gore led Bradley, a former New Jersey senator, by 50 percent to 29 percent in the matchup of the two Democratic candidates.

Bush led Gore 52-42 in a pairing of the two parties' front-runners and led Bradley by 51 percent to 40 percent.

Half said it was at least somewhat likely that Gore could beat Bush in a general election matchup. Just over four-in-10 said it was at least somewhat likely that Bradley could beat Bush in the general election.

The telephone poll of 1,021 people was conducted Nov. 10-11 and has an error margin of plus or minus 3 percentage points, slightly larger for subgroups like Democrats and Republicans.
