- 74% of Republicans and Republican-leaning independents say the Trump administration is doing the right amount to deport immigrants who are in the U.S. illegally. Another 12% say it’s doing too little and 13% say it’s doing too much.

- Nearly nine-in-ten Republicans approve of sending additional U.S. troops to the border (88%) and increasing deportations (86%). More than six-in-ten strongly approve of these actions.

- 80% of Republicans approve of cutting federal funds to cities and states if they do not cooperate with deportations

- 72% of Republicans approve of suspending asylum applications, with 38% saying they strongly approve.

Only that first stat aligns with what you are claiming. Wanting more border / deportations is fully inline with wanting to control immigration. Likewise cutting funds to states not supporting federal law isn't fringe. And asylum applications are clearly broken.

You can want all of those things and still be against eg ice agents raiding a school. It would be more accurate if it focused exclusively on the more egregious ICE activities.

It looks like the difference in the popular vote was 2,284,967 votes towards R. Do all of those 2,284,967 voters demonstrably overlap with that 86% of the polled Republicans? If not, then claiming that a majority of Americans support every incident in the linked article based on the last election, lacks basis.
