66% of candidates running for election again are in another party in 2020; DEM is the most won and PV the most lost | Election in Numbers


Two out of three candidates running for municipal elections again switched parties and present themselves to the electorate with a new acronym in 2020, according to a survey by the G1 with data from the Superior Electoral Court (TSE). Of the 174,000 candidates who were also in the 2016 elections, 115,000 have a new caption.

In the party exchange-exchange, the DEM, the party of mayors and senate, won the most. The caption had a balance of 3.9 thousand new candidates, counting those who left and arrived.

In the past four years, several parties have changed their names and some have merged because of new rules that try to limit the number of captions, such as the barrier clause.

These name changes and mergers are not considered in the survey, which takes into account only effective party changes.

The most common exchange was from the MDB to the PSD. Then, the PSDB also for the PSD.

A specialist in party migration, political scientist Marco Antonio Faganello says the high number of exchanges is due to a recurring practice among the parties, of trying to attract people who have already applied for other legends, because they have experience and votes.

“They maximize the chances of having votes and seats without having to train staff”, says the master and doctoral student in Political Science at Unicamp. “So the migration helps the parties to establish themselves in new municipalities or to increase their electoral ‘corral’. I even have a name for it: they are headhunters parties. They are looking for competitive candidates with an electoral background.”

According to Faganello, a negative effect of this practice is to weaken the voters’ connection with the parties. “The vote gets more and more personal.”

From the candidate’s point of view, it is also advantageous to change, says the expert. “A candidate migrates looking for a better condition to be elected. Perhaps there is some promise that more money or better conditions for the candidate. If the party does not have a local presence, mainly in small municipalities, the candidate can become a leader of that party. in the municipality “, he explains. “It’s like it’s one hand washing the other.”

Fewer exchanges between mayors

Candidates for mayor in 2016 who run again this year switch less parties than candidates for city councils.
