CHICAGO (AP) — Rafi Zelikowsky skipped class Tuesday to camp out in downtown Chicago and wait for Barack Obama, the man who captured the hearts of so many young voters.”We’re feeding off the energy,” said Zelikowsky, a 19-year-old Northwestern University student from Los Angeles who arrived at 7:30 a.m. to wait in a long line outside the park where Obama planned to address his supporters into the evening. Zelikowsky, who voted for Obama by absentee ballot in California, also spent the previous weekend canvassing for the Illinois senator in rural Iowa. That kind of loyalty — and the Obama campaign’s early efforts to harness young voters — appeared to be paying off at the ballot box. Early exit polls showed that young voters were supporting him by a more than 2-1 margin, with his greatest support coming from black and Hispanic young people.—-Contact The Daily Reveille’s news staff at [email protected]
