It would have come off as Democrats making nothing but “making power grabs”

Even if it didn’t have that outward appearance, the liars would have lied to ensure that was the message.

Here’s an example of this with Democrats trying to improve access to voting:

Rep. Barr Denounces House Democrats’ H.R. 1, “The Election Power Grab Act”

Here’s Democrats trying to fix the courts:

“Liberals are furious that [the Supreme Court] is abiding by the Constitution,” said Oklahoma Senator Markwayne Mullin, branding court reform efforts as “a toxic power grab” chipping away at the constitutional separation of powers.

Here’s the Democrats trying to give people in DC access to representation:

Republicans warned the Democrats’ bill is an unconstitutional power grab that will result in the District receiving greater benefits than citizens of any other state

This isn’t hypothetical partisan complaining… the past is littered with examples of Democrats attempting to do the very things that people complain they aren’t doing – with Republicans whipping up lies to feed the electorate undermining those efforts.
