There are still significant partisan and demographic divides, but they’re not so pronounced as to leave the two parties diametrically opposed. Rather, the gap is a matter of degrees.
Americans say, 62% to 29%, wearing masks is a matter of public health, not personal choice.

Most say wearing a mask is equally or more about protecting others than oneself.

Most Americans say they're mostly or always wearing masks when they're in public and around others (e.g. grocery shopping). But it's not all-or-nothing: fewer, for example, do so when outside but not in close proximity to others.

Most people who wear masks at least sometimes say they don't feel like others are judging them for it, either positively or negatively. Just 8% feel like they're being judged negatively for it.
Nearly 70% of Americans say wearing a mask near others is respectful. Just 8% see it as a sign of weakness.

20% of GOP men see mask-wearing as a sign of weakness, compared to 8% of Dem men, 6% of Dem/GOP women.

So: something interesting going on there. But at the same time, even 20% is a distinct minority.
A 63% majority of Americans say Trump and other officials should wear masks. 7% say they shouldn't. The rest aren't sure or don't care.
Oh, one additional note: there is definitely some geographic variation here as well.
Also, perpetual caveats about self-reported behavior for all the questions on mask-wearing, which are vulnerable to social desirability effects.
That being said, if flat-out rejecting masks had truly become a symbolic statement of partisan signalling you'd DEFINITELY expect polls to pick that up.
