.@realDonaldTrump during the #GOPDebate: "I cannot believe how civil it's been up here" https://t.co/WuW36RKMKZ https://t.co/KCtc6flBLv — CNN (@CNN) March 11, 2016 Telegraph writers give their view: Rob Crilly - MARCO RUBIO It was all too late, of course, but the junior senator from Florida sounded like a statesman as he gently corrected Donald Trump on Cuba, climate change and the Middle East. He was assured and confident. Robert Tait - DONALD TRUMP A less toxic debate - at least in terms of personal rancour - than recent encounters, with some real substance as well as self-conscious attempts at civility. But in the last analysis, a stalemate which is going to change very little - and as such, another win by default for Donald Trump. Harriet Alexander - MARCO RUBIO He answered questions about policy fluently and in depth, making Donald Trump's inability to articulate any sort of detailed plan all the more obvious. He made a point of referring to concerns held both by the elderly - he referenced his mother's worries about social security - and the young, discussing fears over student loan burdens. Quick on his feet and informed, he looked sharp and still very much in the fight. Whether the Florida voters think the same will be revealed on Tuesday. Barney Henderson - DONALD TRUMP This was the twelfth Republican debate - and it's starting to show. None of the candidates went on the offensive after the criticism of the last debate, which descended into playground insults. Gone was Trump the (offensive) showman and here was a "presidential" version. Mr Trump was, as usual, far too light on substance and policy to be cast in a presidential light, but neither was he damaged by attacks from any of his rivals. And they are the ones that have ground to make up - vast swaths of it. Ruth Sherlock - NO-ONE Nobody. Marco Rubio had some punchy moments, and Ted Cruz did a better job of attacking Trump (focusing on substance instead of the size of his endowment). But nobody shone and nobody tanked. This was meant to be the most high pressure debate yet, but it hasn't moved the needle. David Lawler - DONALD TRUMP In truth, the front-runner was far from impressive tonight. He once again displayed only a surface-level understanding of key issues including the military and education policy, and his "presidential" restraint could easily have been mistaken for boredom. But he leads Marco Rubio in Florida, John Kasich in Ohio and Ted Cruz - his nearest rival - in the delegate count. None of that is likely to change based on tonight's debate. And that will suit Mr Trump just fine. You can have your say here
