She spent an hour at Al Johnson restaurant in Sister Bay , one day after she released her latest fundraising totals.
"Well I was really pleased by the announcement that I made about how much resources I was able to raise from people here in Wisconsin," Burke said.
Republican Governor Scott Walker also released his numbers Wednesday.
Burke reported her campaign raised $3.6 million from January through June, compared with $8.2 million by Walker.
Burke had $2.5 million on hand, Walker had $7.6 million.
No one from Governor Walker's campaign was available for an interview Thursday.
A spokesperson for Walker said in a statement, "The $5 million gap in cash on hand shows the extraordinary enthusiasm behind Governor Walker's campaign to continue moving Wisconsin forward."
The statement continued to say, "As an out of touch Millionaire, Mary Burke clearly has had trouble connecting with her base."
Mike McCabe is the executive director of the Wisconsin Democracy Campaign, a group which tracks political spending.
While Walker and Burke say their numbers show strong support from voters, McCabe has another view.
"These are staggering sums of money that are being raised. Obscene sums of money that are being brought in to fuel these campaigns," McCabe said.
"This shows the extraordinary enthusiasm of the donor class."
Burke faces a primary challenge from State Representative Brett Hulsey of Madison.
He has yet to report his fundraising totals.
She plans to continue campaigning Friday through Door County with stops in Sturgeon Bay, Ephraim and Bailey's Harbor.
