You have reminded us all of the key. At this time there are "checks and balances" as in civilized nations and the past version of the US the Founders envisioned.
Once Walter Winchell could squeeze his columns into the hostile William Randolph Hearst newspapers to expose Adolph Hitler when others wanted him ignored or called a breath of fresh air for peace. Now the leftist media is the 100% propaganda arm of the Dems. Watch for FCC to cancel outliers soon.
Once the Senate could stop a wild and reckless House or vice versa. Or the President could veto. Or the SCOTUS could act independently of the current politics, fearlessly. NONE of this is in play today.
