Perhaps the most direct argument against Harris being an ideas candidate with an economic philosophy all her own is that she never articulates what that philosophy is.

When asked about her "opportunity economy" in the rare interviews that she has done, Harris struggles to say what the idea is beyond retelling her personal story and rehashing her calls for a couple of additional subsidies.

Take the interview Harris just did last week with 6ABC Philadelphia anchor Brian Taff. Taff asks Harris to name two policies she has for bringing down prices and making things more affordable for people.

In response, Harris talks for nearly two minutes about her upbringing in a middle-class Oakland neighborhood before eventually getting around to mentioning her plan to give tax credits and subsidies to new small businesses, home builders, and home purchasers.
