The Democrats are desperate to win this seat and that's why they're throwing everything they can at Hyde-Smith hoping something sticks.
They're planning that a 52/48 Senate means a Romney/Collins/Murkowski alliance can thwart Trump (Pubbies can't count on Manchin now that he's been safely re-elected). 53/47 and Pence can break the tie. Alliance is useless.
Espy must win at all costs.
Bingo!
They want to empower Romney/Collins/MooKowSki and create another Kavanaugh circus.
53 eliminates that play.
They are evil and we can’t let them win.
