In Palm Beach County, Tumult Grew Hourly
Reconstruction of voting in Palm Beach County, Fla, on Election Day shows overworked and understaffed system grappling with widespread confusion over ballot originally designed by county's Democratic elections supervisor to be easily read; while majority of voters from both parties cast votes without problems, enough were confused that local Democratic Party office and state Democratic headquarters were deluged with angry calls; voters seeking help from electoral officials say they were turned away by poll workers who, in turn, were told by bosses to remind people they could vote only once; many voters were confused by second hole in punch-card ballot that did not align with names of Democratic candidates, Vice Pres Al Gore and Sen Joseph Lieberman, and ended up voting for Patrick J Buchanan; photo (M)
