Alan Johnson is at it in The Times. Gordon Brown has tried it. The Tories want to play it up, thinking it will affect their support.
Now Harriet Harman in today's Western Morning News tries to cosy up to the Lib-Dems. She urges
Westcountry voters to basically do whatever they can to keep David Cameron out of Number 10, which in most of the region's seats means voting Lib-Dem.
So don't vote for Labour but just stop Cameron.
She said Cameron was "supposed to be the one to watch" in the TV debates, but "didn't win it".
Interestingly, she refused several opportunities to say Gordon Brown did win the debate - and did not mention Nick Clegg by name at all.
