Good luck with the campaign. Without wishing to poop on the party, Filton's death sentence was passed decades ago when the council choked the area with close in development. Just as short sighted then as now, its not a recent development but the final death throes of what has been a tortured process. Look at Woodford in Stockport to see what council support there is for an obvious business case.
Council tax from high density low cost estates will always win. Shame.
