Solo democentristi (32,3%, +5,7%) e verdi-liberali (7,7%, +2,3%) vedranno il numero di mandati aumentare nelle elezioni federali di ottobre, stando ai risultati del sondaggio condotto nell'ultimo trimestre del 2014 all'associazione di pubblica utilità Vimentis.
Liberal-radicali (14,4%,-0,7), verdi (7,6%, -0,8) e borghesi-democratici (5,4%) marcerebbero sul posto, mentre una flessione più marcata l'accuserebbero socialisti (16,3%, -2,3), e popolar-democratici (9,3%, -2,7). Il margine d'errore, avvertono gli esperti, resta per ora compreso tra -4 e +4%.
Un'analoga indagine, pubblicata un mese fa dall'Istituto Léger, dava l'UDC al 23.8% (-2,8), il PS al 19,8% (+0,9), il PLR al 15,7% (+0,6) e il PPD al 12,4% (+0,1).
