DAVAO CITY — Voting in Barangay Centro Agdao is going at a snail’s pace. Lines are long and at the rate the automated voting is progressing, observers fear many will not be able to cast their ballots by the time polling centers close. Voters who have agonized waiting in line grudgingly call the PCOS machines “tikas machines”, with pun intended. Workers, who still have to report for work and those who find the long lines and the wait much too daunting, have already left the precincts without casting their votes.
