This follows our exclusive ABC7 poll that shows Emanuel leading right now with 54 percent of the vote.
Our poll suggested that between February 3 and 7, Emanuel had enough support -- a majority -- to win the election, and that only about 15 percent of voters remained undecided.
So if those numbers hold true,Emanuel's opponent will have to change the minds of some voters, and that could explain their stepped up attacks on the reported front-runner.
Carol Moseley Braun repeated a now familiar demand that Emanuel explain his activities after he left the Clinton Administration and before he was elected to congress.
She says voters need details about what Emanuel did on the board of scandal-plagued Freddie Mac, and how he made $18 million during the same period as a lobbyist for an investment firm.
"I think he has to have more disclosure, more transparency about what did and did not happen," Moseley Braun said.
"I heard a lot about attacks, but I don't know if you saw this one or got this in the mail," Gery Chico said.
Two hours later, Chico -- in another event focused on what he calls the "Rahm Tax" on services -- accused Emanuel of distorting Chico's image on a campaign flyer.
"First of all, this isn't even me. Talk about false advertising, this is some other guy. He cropped the head on top of some guy that's obviously heavier than me. I don't own that tie and I don't own that suit," Chico said.
ABC7's survey of 600 voters released this week indicates that 54 percent would vote for Emanuel.
On Election Day, that majority would make the former congressman a first round winner.
Chico at 14 percent, Miguel del Valle at 8 percent and Moseley Braun at 6 percent are trying to keep Emanuel below 50 percent to force a runoff between the first and second place finishers.
Chico was asked what he would say to change the minds of people who planned to vote for Emanuel.
"You're not getting straight talk. You're getting evasion just like you are on this tax, and I hope that everybody is taking a second and third look at this thing because this does not add up," he said.
Emanuel did not have a public schedule Thursday, and the campaign has repeatedly denied any wrong doing during Emanuel's time in the private sector.
An Emanuel campaign spokesman had no comment on the Chico flyer.
You will get a chance to hear more from the candidates at 7 p.m. Thursday, February 17 when they debate on ABC7.
It will also be streamed live on www.abc7chicago.com.
