From left to right (from the TV viewer's perspective), two sentences on each candidate's performance in last night's CNN debate:
Rand Paul tried hard — perhaps too hard — to go after Donald Trump, with modest success offset by his coming across as slightly whiny. His answers continue to offer an interesting and unusual perspective, more focused on liberty and the Constitution than many of the others, but his campaign nevertheless feels like its tires are spinning badly.
Mike Huckabee made a particular effort to be upbeat, to avoid criticizing other Republicans, and to make a strong moral case in the few questions that came his way. However if you imagine each of the candidates being asked “Why do you want to be president?” he's the one I have the hardest time imagining answering the question adequately.
