Vice President Bush continues to hold a "commanding lead" over his nearest challenger for the GOP presidential nomination, Kansas Sen. Robert J. Dole, according to a Gallup Poll released today. Bush leads Dole 47 percent to 22 percent compared with 40 percent to 19 percent two months ago. The other candidates are far behind, between one percent and 7 percent. Only 15 percent of the Republicans surveyed said they are undecided.

Despite intensive campaigning and several televised debates, none of the Democratic presidential candidates is winning much new support.

According to the Gallup Poll, 43 percent of Democratic voters remain undecided, about the same as two months ago. Jesse L. Jackson leads with 22 percent followed by Massachusetts Gov. Michael S. Dukakis with 14 percent. The remaining candidates draw between 5 and 8 percent, with former Arizona governor Bruce Babbitt at the bottom with one percent. The poll indicates almost no change from a late August poll.

With one year until the election, apart from Jackson, who is recognized by 96 percent of those surveyed, the name-recognition level of the other Democrats is 38 percent to 49 percent. On the other hand, Gallup noted, "most Republicans rate highly on name recognition." The exception is former Delaware governor Pierre S. (Pete) du Pont IV who rated 34 percent -- the only one of the Republicans known by less than half of those surveyed.
