(CBS) — Two polls released by the Chicago-based polling firm Ogden and Fry show Mayor Rahm Emanuel continues to have an edge over his opponent, Cook County Commissioner Jesus “Chuy” Garcia a few days ahead of the election.

In a poll conducted on April 4 among 972 respondents, Emanuel led Garcia 51.3 percent to 33.0 percent with 15.6 percent undecided and a margin of error of +/- 3.21 percent.

In a poll conducted on April 3 among 838 respondents, Emanuel led Garcia 56.8 percent to 43.4 percent, with no undecided option and a margin of error of +/- 3.45 percent.

Last week, Ogden and Fry polls had Emanuel leading Garcia 57.9 percent to 42.1 percent without an undecided option and leading 47.6 percent to 34.2 percent with 18.3 percent undecided.

Analysis by Ogden and Fry attributes Emanuel’s lead to the wave of negative ads against Garcia. Ogden and Fry says the Hispanic vote does under-poll, noting that Garcia finished 7 points higher in the primary election than he polled.

Both Emanuel and Garcia spent Easter Sunday campaigning.

Garcia started the day at his neighborhood church, with his wife and two of his grandchildren. It was the first of four church services he attended.

Reverend Jesse Jackson was with him for much of the day and the two moved to one of President Obama’s favorite breakfast places, Valois, in Hyde Park.

Garcia talked to reporters there, linking the holiday and the campaign.

“I think Chicagoans also feel a sense of renewal, spring is here and I think the winds of change are blowing through Chicago,” Garcia said.

Mayor Emanuel was feeling it on the Southwest Side Sunday afternoon at the Monument of Faith Evangelical Church. His wife Amy, who isn’t usually on the campaign trail, was there today, greeting churchgoers.

The mayor took no questions before or after his event, his campaign saying his only contact with reporters would be before Sunday night’s Cubs opener.

He also for the most part ignored his opponent, concluding his comments with a reference to celebrating Passover.

“On that holiday, we remember the journey to freedom,” Emanuel said. “We’re on a journey as a city together, and our destination is where our children have a better life.”

Both candidates were at Wrigley Field for the Cubs home opener.
