Since quitting, her efforts have been primarily about building up the Palin brand and its fortunes (which is fine except for the quitting part).
Her support of conservative candidates has been a positive thing.
Her grabbing (or making) headlines by being confrontational has served a purpose (multiple purposes in fact, including personal enrichment).
Certain folks here say that she had to quit in order to devote herself to running for the White House but that's nonsense. If she had not quit she would be a private citizen today with plenty of time to set-up a campaign. The fact that there are almost two years left and nobody has declared yet shows this.
And, nothing she has done since walking away from public office has done even a little bit to enhance her very slim CV or make her better qualified for the toughest job on the planet.
Reality TV, book tours, Facebook/Twitter, paid speaking engagements, sitting in the audience of DWTS all keep her name viable and profitable but they are not the stuff of effective Presidents.
That's an outright lie. Nobody here has suggested such as a thing except some of your PDS buddies.
