HARTFORD, Conn. (AP) _ Republican George Bush has caught up with Democrat Michael Dukakis in a poll of Connecticut voters released Friday.

The Hartford Courant-Connecticut Poll showed that state voters, who favored Dukakis by 17 percentage points in July, now prefer Bush for president

over Dukakis 39 percent to 37 percent.

But because of the 5-point margin of error for the poll, it is impossible to determine which candidate is in the lead. Also, about 20 percent said they might change their minds between now and Election Day.

The poll was taken by telephone from Sept. 12 to Sept. 18. Conducted by the Institute for Social Inquiry at the University of Connecticut, the pollsters surveyed 512 people who said they were registered to vote or would be by the state's Oct. 18 deadline.
