Past trouble spots could flare again Tuesday

(CNN) - Registration and absentee ballot issues topped last-minute concerns among voters in the days before Tuesday's presidential election, with one analyst predicting previous flashpoints may cause headaches again this year.

Of the more than 11,000 problems reported to CNN's Voter Hotline so far, the largest number of complaints - more than 1,500 - come from Florida, where a hotly disputed recount settled the 2000 election. Another 450-plus originated in Ohio, where massive election-day turnout delayed the count in 2004.

The biggest complaints were early voting lines stretching for several hours, names that did not appear on voter rolls or absentee ballots that never reached the people who requested them. Similar patterns showed up among callers nationwide.
