But 71 percent said they think he will.Even still, the survey found high approval ratings for Bush, who took office Friday as the 41st president. Respondents voiced high expectations for his presidency and gave him strong marks for his Cabinet choices.

A solid 59 percent said they viewed Bush favorably, precisely the same approval rate Prresident Reagan received in a Media General-AP poll last spring. Only 25 percent rated Bush favorably.

Bush fared well in another comparison with his popular predecessor: Expectations for his presidency came close to the ratings of Reagan's performance in a Media-General-AP poll conducted this fall.

Although many respondents were unfamiliar with Bush's nominees for his Cabinet, those who did have opinions were strongly positive. Overall, 45 percent said their impressions was that the Cabinet was a good one and 8 perecent called it excellent.
