With David Cameron refusing to take part in the BBC debate last night, the broadcaster framed the show as a chance for the "challengers" to have their say.
That meant all the opposition parties, Labour, Ukip, Greens, Scottish National Party and Wales' Plaid Cymru.
So no party that was part of the government was able to take part.
Even if they wanted to.
And Nick Clegg did want to take part.
And he really, really wants you to know that.
As I said earlier, I was not invited to #BBCDebate. I would have happily taken part and proudly defended our strong record in government.— Nick Clegg (@nick_clegg) April 16, 2015
The prime minister said he wasn't invited. “I’m a polite individual and if I’m not invited, I’m not going to try and gatecrash it," he told reporters. That's not completely the whole truth, Cameron ruled out taking part in any debate during the short election campaign and agreed to only one, seven-way debate, which took place two weeks ago.
Still, everyone wanted to know where David Cameron was.
According to the Guardian, the second most searched-for question on Google during the debate was: “Why is David Cameron not at the debate?”
But no one asked "where is Nick Clegg?"

Miliband repeatedly brought up Cameron's absence, even on Twitter, challenging him to a head-to-head debate.
.@David_Cameron I believe my plan can give this country a better future than yours. Disagree? Prove it - debate me & let the people decide.— Ed Miliband (@Ed_Miliband) April 16, 2015
Still, this might be a blessing in disguise for the Lib Dem leader, because it achieved the near impossible. Making people feel sorry for him.
He's made a lot of mistakes, but in the end Nick Clegg's just a boy standing in front of another boy, asking him to debate him.— Hopi Sen (@hopisen) April 16, 2015
Will someone please debate with Nick Clegg? Pay the guy some attention, stop him feeling sad. Come on.— Iain Martin (@iainmartin1) April 16, 2015
At this point, Nick Clegg probably challenges the milkman, newsagent and PPI cold callers to a debate.— Mark Wallace (@wallaceme) April 16, 2015

So we'll humour him and ask 'Where was Nick Clegg?'
Oh alright, actually, he was having a pint in his constituency.
Enjoyed my time on the doorstep this afternoon in Ecclesall but canvassing in the Devonshire Arms is even better! pic.twitter.com/fRAMhy2Pfu— Nick Clegg (@nick_clegg) April 16, 2015
