Seems to me like they're simply implying that the GOP knows they can't beat Democrats on policy so they create this Communist Strawman to scare their constituents. It's pretty basic GOP SOP.

Republicans aren't afraid of democrats because dems aren't a threat to republican power. Republican policy threatens the lives of millions of women, children, bipoc, lgbtq+, etc., but dems can only stave off the worst abuses, such as a second trump term (they'd better be able to, so far looks like he's cooked) or launch a campaign once the rights have been taken away. And yes its true, republicans and democrats get funding from many of the same sources, democrats have even funded goofball republicans they thought would be easier to defeat (see desantis, trump). Republicans have nothing to fear from a democrat. I am wishing that democrats were more self reflective of these reasons and many others; but rather than do an ounce of self reflection "the only obvious" take you could get made no sense. Its sadly quite telling, as to how otherwise good, intelligent people are able to believe and adhere to the nonexistent "back to brunch" political program of the democrats.

Hope that clarifies my perspective for you a smidge
