CLEVELAND -- U.S. Rep. Dennis Kucinich is taking on Secretary of State Colin Powell in a political showdown over the possible war with Iraq.

The congressman appeared Sunday morning on "This Week with George Stephanopoulos" on ABC as a voice of peace in an age of possible war.

Kucinich (pictured, left) confirmed for NewsChannel5's Angie Lau that the national spotlight might thrust him into a presidential bid.

"People are very concerned (that) if this country goes to war, will there be more terrorist attacks in this country? Will their loved ones sent to Persian Gulf be safe?" he said.

Powell urged the United Nations' Security Council this week to act against Iraq. Kucinich said that decision would be a mistake.

"Iraq has not attacked the United States, (and) it wasn't responsible for 9/11," he said. "We have to do everything we can with diplomacy and containing Iraq so as not to launch (into a) war that would have devastating consequences."

Sunday's appearance on "This Week" is one of many national appearances by Kucinich, leading to murmurs across the country that the Clevelander may be a viable presidential candidate.

"I'm considering that people are asking me to take another step, (and) I'm listening to what they're saying," he said.

Kucinich said that a decision is imminent.

"(It's) such a large question to think about, but that decision will come sooner than later," he said. "But it's likely to be sometime soon."

He's gaining support as a popular voice in a perhaps unpopular war, at least for 50 percent of Americans if the United States isn't backed by the United Nations, according to the latest Newsweek poll.

"We don't want to go at it alone," Kucinich said. "If we go at it alone, then we're stuck alone."

The presidential question is something a lot of people are starting to talk about.

Kucinich receives between 200 and 400 e-mails a day from people across the country who urge him to run.
