Nope. I was among those comparing Gingrich to Churchill....before the Churchill/Gingrich article came out, btw.
This Grant connection makes sense, though, given Grant’s supposed flaws regarding alcohol. Those were probably trumped up charges against Grant, but aren’t political charges almost always trumped up?
There's no doubt Grant loved cigars (he died from throat cancer), but the charges of alcoholism seem to be no more than rumors started by jealous men.
