Walker says his strong fundraising should remove any doubts from those who wondered whether he could raise the money needed to mount a successful campaign. Concerns over his fundraising ability led to his dropping out of the governor's race in 2006.
Doyle campaign spokesman Mike Edmondson says he believes the governor is in a "very competitive" position. But he says Doyle has been focused on his job as governor, not raising campaign money.
Doyle has $2 million cash on hand and Walker has $1.1 million.
