James Hohmann: “If Joe Biden fails to catch fire in Iowa on his third try for the Democratic nomination, Sen. Amy Klobuchar will be well positioned to make inroads with the kinds of voters who might otherwise back the former vice president.” “The senator from Minnesota has been getting a more positive reception in the Hawkeye State than has been reflected in the polls, where she’s in the back of the pack, or in the national media’s coverage, which has focused more on candidates like Biden, Bernie Sanders and Beto O’Rourke.” An important point: “Klobuchar said she thinks the televised town halls by the cable channels this year will wind up being equally as important as the debates, which will be split across two nights and where the massive numbers of candidates on the stage will make it hard for anyone to get a word in edgewise.”
