To anyone reading Ensign's comment and downvoting, their claim is essentially an already established fact. Rolling Stone put out an article after the election saying that the Harris campaigned intentionally ignored Democratic party insiders and their advice and polling data against bringing the Cheneys on board.
A Democratic strategist says they warned key Harris surrogates and top-level officials at the Democratic National Committee that campaigning with Liz Cheney — and making the campaign’s closing argument about how many Republicans were supporting Harris — was highly unlikely to motivate any new swing voters, and risked dissuading already-despondent, infrequent Democratic voters who had supported Biden in 2020.
“We were told, basically, to get lost, no thank you,” says the operative.
The campaign was complete garbage, though. In a Rolling Stone article, it details on how many advisors and Democratic party operatives were begging her campaign to not bring in Liz Cheney because any gains would essentially be eclipsed by other Democratic voters that otherwise stayed home.
I also understand that your main points are on how political commentators and news anchors on TV chose not to encourage Harris to tackle issues on the economy, but an Atlantic article essentially tells us that Harris torpedoed her anti-big business rhetoric when she brought in her brother-in-law into the campaign itself.
Honestly, how big of a role does media have in swaying her campaign into talking about important issues (such as the economy, like you pointed out) if she willingly chose to ignore the easiest slam dunks her campaign had?
