Many Republicans are feeling optimistic about Trump’s reelection in 2020. The Mueller investigation, on which Democrats’ pinned their hopes for mortally wounding the president, has crumbled like a bride’s first pie crust. AG Barr, unlike the lollygagging Jeff Sessions, is vigorously investigating the corruption in the FBI and DOJ that led to government agencies’ interference in an election in favor of Hillary Clinton, and then their attempts to engineer a bloodless coup to remove a legally elected president. The economy is roaring, with numbers on growth, employment, and productivity not seen in decades. And international rivals like Iran and China are now being confronted rather than coddled.
