I don't think so
Lib Dems are not going to be in power next week, so its safe to say that their energy policy isn't going to take hold, especially as the two other major parties are strongly pro-nuclear. Its safe to say that the UK will be building new nuclear plants, even if you do vote Lib Dem tomorrow.
Its also safe to say that voting Lib Dem isn't going to commit us to a firey death from some rogue state's ICBM. Its never going to happen, so please limit your fearmongering to this year's acceptable topics, such as terrorists and immigrant paedos.
I heard the Lib Dem's were going to give kids swine flu. Oh hold on, my mistake that was last year.
