You raised two things. First, Support for “For the People Act” was published by Newsweek:

“More than two-thirds of likely voters (68 percent) said they would back the proposal. Just 16 percent said they opposed it. The support also transcended party lines, with 70 percent of Democrats, 68 percent of independent or third-party voters and 57 percent of Republican voters expressing approval for the bill.”

Now, your point about Voter-ID, yes, you’re right that a majority of Americans support them, but context is important. Most surveys are from 2016, and not much from the past year or so, when the topic really reached public discourse. Nevertheless, this AP Survey from 2016 shows 91% of Republicans support voter-ID, compared to 58% of Democrats. So yeah, they do too, but this is in the context of automatic voter registration when you get your ID, such as a driver’s license or other government ID. Here, 47% of Republicans support it, whereas 67% of Democrats do. Similarly, on the question of sending mail-in ballots to “every registered voter” and allowing voters to receive them without excuses is supported by 78% (D) to 27% (R).

Look, what are we really arguing about here? Republican politicians and strategists aren’t even pretending to hide their goals here. All Republican strategists know that Republicans win elections when voter-turnout is low — the lower, the better for R’s — and this has been the case for decades. In 1980, Paul Weyrich, a leader of the modern conservative movement, told a gathering of religious leaders, “I don’t want everybody to vote. As a matter of fact, our leverage in the elections quite candidly goes up as the voting populace goes down.”

That article gets into many more details and stats.

The Big Lie about the stolen election is the pivot on whether to support HR1 and HR4.
