Seat Tipping - Labour's Potential Long Term Disaster

Reading Jackie Ashley's column where she stated that some Labour politicians got me thinking: how many Labour seats are going to "tip" to the Lib Dems.

One of the things about the 1997 election was how much tactical voting occurred. People who desperately wanted the Conservatives out chose the strongest opposition candidate in their seat, whether Lib Dem or Labour. It's one of the features of wretched First Past The Post voting systems.

Now, if Labour don't get their vote out, or if voters who are left-leaning decide that they can't stand Labour any longer, then the LDs will get that vote. Which could mean that following the election, a lot of seats may end up with the LDs in 2nd place, which could then lead to them holding a lot of 2nd places come the following election.

Could we see a hung parliament in 5 years time?
