I still don't understand this poll and the results
Peru, CPI poll:
"What kind of regime do you believe is the worst that could happen to the country?"
Chavista: 35%
Communist: 24%
Populist: 12%
Ultraliberal: 8%
Fascist: 5%
Ultraconservative: 4%
Unsure: 12%
Fieldwork: 6-11 March 2021
Sample: 1,300
I don't think that the results of this poll and Castillo being the first-placed candidate contradict each other, because Castillo has won less than 20% of the vote. (The field in Peru is extremely fragmented, and in such situations the two-round system is inadequate.) And voters do often simultaneously hold contradictory political stances!
The polls didn’t even show Castillo in the top 6!
AFAIK Castillo has surged in the last days of the campaign. And I'm recalling that there were even polls where he was the second.
