There is just so far Hannity can take this on his own. He does not have a literary editor on staff. The National Review does. So do the Weekly Standard and the Washington Times. For reasons not fully clear to me, they have chosen to turn their back on this whole topic for the last two-plus years.
If, however, these journals continue to ignore the fact that a leading candidate has publicly accused the sitting president of massive literary fraud, they deserve to be taken no more seriously than the Daily Kos.
