Yup let us actually look at that Gallup poll.
Gun control is the forth most important issue for Demand D-leaners, behind healthcare, how women are treated, and income/wealth inequality.
It is lower for GOP/leaners, fifth, behind the economy, immigration, taxes, and healthcare.
The poll would have been more useful if they broke it out by urban v suburban v rural or by leaners or independents only. I’d be most interested in knowing how many R leaners (those who never or no longer are calling themselves R but have previously voted that way) rate gun control.
Overall it seems that this data suggests that being against moderate gun control measures will hurt in a general more than help.
One thing is clear though: a D who is not for some degree of gun control will piss off more D/leaners than win anyone over who is against some control.
By definition of course “too radical” is too much but how much is too radical? Any control position will be painted by the NRA as “too radical” and most who are swingable I think are going to discount what the NRA says.
Reality of course is that gun rights are secure no matter how radical a president’s position. Congress can pass some mild control maybe, if a president uses the office as a bully pulpit effectively and has D control of both Houses, but even that is a non-issue without control of both sides.
Detailed polls that matter the most are swing voters in PA, MI, and WI. What voters in Alabama or California think about this matter little.
