Kamala Harris running a damn near flawless campaign, with just a month 1/2 of campaigning.
There’s a few major flaws:
Trying to out-flank republicans on the right with immigration and crime; instead of counter-messaging that republican claims of migrant crime are false and migrants commit less crime than average, and crime as a whole is declining, her campaign promotes how tough she is on crime. This is essentially campaigning for the republicans. The people who are terrified of immigrants and criminals are voting republican.
Trying to out-flank republicans on the right in foreign policy. Harris can promise rivers of Muslim, North Korean, and Russian blood, and the people who want that will still vote republican. Talking about how lethal the US military will be and how hostile the US will be to other countries decreases turnout. War is not popular. Trump’s campaign is already hitting Harris on supporting the genocide in Palestine.
