It's the second year in a row that Murphy has traversed the state during Congress' August recess.
"I set out to do this last year because I figured that there was no better way to be able to accurately represent what Connecticut wants in Congress than walking across the state and talking to anyone that would be willing," Murphy told a ring of supporters in Rogers Park.
Congress has an approval rating of about 7 percent, Murphy said. "People don't think we listen," he said.
In an interview Murphy said health care and the recent clash in Charlottesville, Va. between white nationalists and counter-protesters were among the national topics that came up in his conversations, though "bread and butter" issues like schools and public safety were just as common.
"I've never seen the level of interest in politics and government that there is today," he said. "The issues that we're talking about in Washington are deeply personal, whether it be immigration or health care, the things Donald Trump is talking about doing would hurt thousands and thousands of people in this state. And that's why they're turning out."
State Rep. Bob Godfrey, D-Danbury, likened Murphy's walk to the knocking on doors that legislative candidates undertake every election year.
"You can't doorknock the entire state of Connecticut but you can stay in touch just by talking to people," he said.
