Mainstreet "*" = Mainstreet does not mention "Other" nor any other party than the main four, but the total of the main four is 100%, (±1% because of sum of rounding errors). It is not known whether any other parties were allowed in the answer, or whether those answers were excluded, but it is highly unlikely that less than 0.5% of those polled by Mainstreet prefer a party other than the main four. |} Polling by language group French
