The Republican nomination race reminds me of an old nursery rhyme:
Letter of the Day (Jan. 31): Republicans

There once were two cats of Kilkenny
Each thought there was one cat too many
So they fought and they fit
And they scratched and they bit
'Til except for their nails and the tips of their tails
Instead of two cats there weren't any
