Former Florida Republican Gov. Jeb Bush is running for president. (Maybe.) But just how much does he have in common with his brother, George W.? His Twitter page might offer a clue. The first human Jeb followed on Twitter was none other than his brother’s former deputy chief of staff—Fox News analyst Karl Rove. So is the Oracle of Ohio going to be back in the fold come 2016? We can only hold our breath. Or perhaps Jeb just likes Rove’s engaging Twitter personality. (Full disclosure: the first person I followed on Twitter was Chuck Grassley.)
