I had a look at the form, and it's really a mess. It's like they tried to make an accessible form, but failed.
Which is way worse than simply not doing anything. Generally browsers are decent at making sense of what they're told, even if it's not perfect. But they've gone out of their way to tell the browsers how to behave for these polls, and have done it incorrectly.
There's a radiogroup role without any sort of labelling, no aria-checked flag on the radio items themselves (this may be implicit in the radio control, but I always prefer to err on the side of caution in that regard, to avoid browser behaviour differences), there's no fieldset to group the items, and no legend to describe the form, or the group of radio buttons. They've got two headings for the form, why not use them for the proper labelling?
Then I saw that the submit button had a manually set, non-zero tabindex attribute. Which is all kinds of stupid, and will just completely destroy anyone's ability to easily navigate with just a keyboard.
And all that in such a simple form.
So @DaptoFunlandGuy I completely understand your pain, if you need to use any sort of assistive technology.
