This is highly unlikely to cause a statistically significant difference in the polls. Having this strong of a view point on the matter is largely isolated to a specific demographic of younger, progressive voters, who are notoriously difficult to reach and accurately account for via traditional polling methods.
It registers as the 15th most important issue via a Gallup poll, and that doesn't account for which "side" the individuals polled support.
Of the 30% of the population saying it is an "extremely important issue," it gives no indication of what their desired resolution is.
On the extreme end of the spectrum, consider that 30% of our nation is in a death cult that believes Israel plays a role in their eventual salvation, not to mention how many people are blatantly racist and view anyone with darker skin as a terrorist.
I am registered, politically active, not difficult to locate and have had the same phone number for 20 years, yet, I MIGHT have been polled once in that time!
This isn't to say there aren't those who are doing as they say, but it is not likely to move polls one way or another.
Adding to this, the wealth disparity is going to continue to increase with those who have equities dramatically increasing their personal capitol, while the middle class is going to fall further behind.
I'm convinced a major part of inflation that goes completely ignored is the staggering amount of wealth generated by equities. People have literally seen 1 million become 2 or 3 over the last few years. They have been spending money with complete disregard... Watching what people buy at Costco is insane!
