Texas Gov. George W. Bush continues to enhance his lead in the polls over Vice President Al Gore in the 2000 presidential race. Despite what we believe about the value of polling at this time in the contest, Bush's success on the campaign trail contrasts with Gore's constant difficulties (with staff, corruption charges and creating a "persona") and is beginning to define a pattern that may continue. Over the past week, Bush has jumped into a 52-39 lead over Gore in a CNN-USA Today-Gallup poll; up from 48-44.

Give Bush credit for staying on message, focusing on issues that can expand his base and basically appearing to be a very likable man. The vice president, meanwhile, is wrestling with Justice Department investigators who are questioning his answers in recent interviews relating to his role in the 1996 campaign finance problems and reworking several of his issue stances.

More and more, I am hearing criticism of Gore's current persona, the casual candidate. Golf shirts are fine for golf, but to campaign day after day in them is wearing thin. He does not look serious, and every picture tells the viewer that he is costumed . . . not natural. But how does he get back to the proper, suit-wearing vice president? If he switches now, he will be seen as "remaking Al Gore" again. He's got to get himself centered and balanced so that he can focus the campaign on the issues that can help him win. Bush is doing that very well.
