No one has been able to solve the complicated issue of immigration and undocumented immigrants coming to the U.S. border, yet Ms. Harris is charged with solving it. As the child of not one but two immigrants and the No. 2 leader of an imperial nation, she is the one charged with telling people in Guatemala “do not come” to the United States. She undertakes tasks at the pleasure of the president, but this particular role reminds me of Admiral Ackbar’s declaration in “Return of the Jedi”: “It’s a trap!” If she is somehow miraculously able to detangle the complex “immigration crisis,” she will be heralded by some, but not all, as a success and worthy of the Democratic nomination in 2024. If she becomes only the latest leader (in either party) who cannot solve the problem, she specifically will be viewed as a failure. The role of the vice president has always been undefined, left largely up to the president to shape. Ms. Harris is clearly not a yes man like Mike Pence, the one completely running the show like Dick Cheney or an institutional encyclopedia and counsel the way Mr. Biden was to Mr. Obama.
