Naperville’s longest serving mayor will seek his fifth term of office in April.

Mayor George Pradel said Wednesday afternoon that a heart stress test had positive results Tuesday, and he will again seek the mayoral post.

“It came out that the blood in my body is flowing real well,” Pradel said, adding he’s received the blessing of his family to run again, along with clearance from his doctors. “I feel like a million bucks.”

The four-term mayor, who has served since 1995, had a history of heart problems.

Pradel will be facing City Councilman Kenn Miller, who also announced his candidacy for mayor Wednesday.

Miller, a councilman since 2005, formed an exploratory committee earlier this year to gauge support for the campaign. In a press release sent just after midnight Wednesday, Miller indicated he would focus on job opportunities and business development in his campaign for mayor in the 2011 election.

“It’s all about jobs,” Miller stated in the release. “I spent the entire summer talking to folks throughout the city, and they agree that this is a critical time economically that requires a focused approach to business development and business retention.”

Pradel pledges to run a positive campaign, and he is excited Miller will be a part of the race.

“A lot of his friends are my friends,” Pradel said, adding that he believes Miller has put a lot of work into his decision to run.

Pradel said much of his campaigning will begin after the November elections, when voters “vote for the people who give (the city) money.”

He said he and his opponent have much in common, and both will be focusing on job creation in the city. But Pradel said he will also be looking to unite the city under uncertain financial times.

“(I will) be looking to bring this city together during these times when the economy is down,” he said.

Candidates must file nominating petitions with by Nov. 22 to earn a spot on the April ballot.
