It’s not necessarily the vote itself that does all the heavy lifting. Politicians pay a lot of attention to the stats of which groups are consistently voting and which issues are important for them, much more so than for what is important to the population at large because their bottom line is appealing to the people who show up to vote. Even if those votes are associated with their opponent if it’s a big enough block then throwing a bone to attract their vote becomes appealing.

For example, old people are one of the most highly consistent blocks of voters and (in our aging society) a growing one, too. Everyone wants to appeal to them as the math gets a lot harder if old people totally reject you! So with politicians competing for their support, social security & medicare make up over 50% of all the increase in government spending (not including more interest in the loans to pay for that which is also very substantial), even though the government already spends six times more on the average 65+ person than on the children and young adults <26, despite the latter group being substantially more likely to be in poverty. It’s not an economically sound decision, investing in the youth would provide better returns for society by setting them on a better trajectory for all the working life they have yet to live. But most of the ages in that younger block are not allowed to vote and the older near 26 are very inconsistent at voting, so their concerns really do not matter to politicians except insofar as the children are a concern of their parents who are much more likely to be voting.

Even if a movement is very popular with the general public, if that movement isn’t in the habit of voting politicians aren’t likely to stick out their neck for it if there are other more reliable voters they can appeal to. Because that would be seen as a wasted effort that won’t help them to win. But if a generally unpopular movement or view is popular with voters then politicians will tend to stand by it no matter what the general public has to say.

Dr. Oz is also nuts so it was kind of cooked regardless of what happened past the primaries
