At Monday’s debate, Hillary Clinton reiterated her promise to make college “debt free.” Donald Trump wouldn’t put a word in against the notion. The Republican National Committee fact-checked Clinton’s claim, pointing out that due to room and board costs, her plan for free tuition wouldn’t necessarily make college “debt free.”

That’s true, but it’s odd to see Republicans imply that Clinton’s plan isn’t profligate enough. If elected, this is likely to be Clinton’s signature domestic policy initiative, and Republicans seem singularly unprepared for it.
