The Economist Reports:
“In a landmark judgement last month the supreme court upheld a ruling in March by the federal electoral tribunal which outlawed party switching.
Some 36% of members of the lower house have switched their loyalties over the past 16 years, some several times during a single term, according to Octavio Neto of the Fundacao Getulio Vargas, a business school.”
From what I understand they switch parties to gain votes in different election years. They get elected for being against the government but then change to a pro-government party so that they can get pet projects in their districts.
This is very rational if it works. The mobs and masses, just like here in the U.S., often don’t educate themselves well enough to understand what the party changing was meant for.
I wonder what the U.S. would do since we only have two parties and some people just vote party line. We did see a situation with Joe Liberman who was treated badly by the Democratic Party and switched to be an Independent. But he may have not had that same win if he switched to the Republican side.
