The Tories are in danger of desperately gnawing through the very lifebelt they may need after 7 May. Put that to senior Tories and they acknowledge the problem but feel they can do no other.
Meet Ed Miliband on the road right now and you meet a very ebullient person. He's more consistently relaxed and confident than close aides can remember.
If he did get back in, what sort of David Cameron would we see? The long gone husky-cuddling eco-warrior won't make a reappearance presumably.
As the Ukip leader tells it, he saw the light in a bar in 1990, on the day the UK entered the exchange rate mechanism. Since then, his mission has mushroomed into something much bigger.
The main thrust of Mr Cameron's interview was an attack on the SNP. Andrew Marr said the PM was beginning to sound like an English Nationalist, which went down pretty badly.
The Tories wanted to play what they see as their good management card at today's manifesto launch. But their plans still contain some smoke and mirrors.
Labour proclaims a "fiscal responsibility lock" in its manifesto - but the IFS says his rules are so vague as to give him a lot of wriggle room.
Our YouGov poll adds to Labour's gloom in Scotland with one tiny qualification. There's a chance the headline figures for MPs elected are a bit better (or less awful) than it might seem.
Following the apparent success with voters of Ed Miliband's non-dom policy, the Tories have focused on Trident and the effect the SNP in a kingmaker role could have on the UK's defence policy.
All is not stable in every part of Labour's ethnic minority vote, and it may suffer from a failure to act on this - if not at this election, then at the next.
Jim Murphy was much more on his best form than yesterday at the second Scottish leaders' debate, taking on Nicola Sturgeon on the issue of "full fiscal autonomy."
Tony Blair would look disloyal if he didn't raise a finger to help his successor. He's already sprinkled £106,000 around local parties - not all of it welcomed with open arms.
Michael Gove calls Nicola Sturgeon a "debutante" and a "very impressive one", as the First Minister received praise for her performance in the leaders' debate.
