It's not surprising from the perspective of the last few weeks," said Larry Sabato, a national political observer, who gave credit to Walker for getting out early."Some contenders look good on paper, but when they actually get out on the stump they fail to live up to their own hype," Sabato said. "I think he suffered a bit from a lack of preparedness."
Sabato said Walker seemed especially unprepared on foreign policy issues.
"He relied too heavily on a memorized speech," Sabato said. "People talked about Scott Walker, the automaton."

American Federation of Teachers President Randi Weingarten, had a different take.
"As Governor Scott Walker leaves this race, this is much clear: You can't build a campaign by tearing working people down and attacking their aspirations for a better life," Weingarten said.Journal Sentinel
