Nadine Dorries' seat is up for by-election. There is a lot of tactical voting going on in by-elections to keep the conservatives out. LD and Labour are neck and neck in the polls. If neither side give way then conservative could take the seat back.
I can see why both are standing firm. At least this way they get a proper feel on which party is the most favoured between LD and Lab. This will make it an easier choice on who will give way at the general election proper, which could be less than a year away. This seat will be ran again when a GE is announced.
"The Liberal Democrats (a centrist political party) will demolish this whole place": Mid-Bedfordshire by-election duel could lead to a Conservative win.
If the Liberal Democrats could encourage their supporters to vote Labour strategically, they might prevent handing the election to the awful Conservative Party. But parties in first-past-the-post systems rarely manage to swallow their pride for the greater good.
Translated it reads: "The Liberal Democratic Party will ruin everything" competition between two left-wing parties in mid-Bedfordshire by-election could split votes and result in a win by the Conservative Party.
