I've heard this kind of assessment before, but I don't really get it. Let me explain why.
The GOP is basically a fascistic party. There are splits within, but by and large its members are committed to absolute hierarchy. Patriarchy is the rule; women can participate so long as they do not upset the hierarchical structure between man and woman (and leave unquestioned the power of perhaps the ultimate patriarch--corporations) . Racism takes multiple forms (dog whistle, birthirism, etc.) and POC can participate so long as they accept their subordinate position. For years, the GOP harnessed the black magic of racism against others, but now the chickens are coming home to roost; if they don't support the fuher, they too will be voted out, or worse, subjected to mob violence. And of course, the GOP denies science and math.
To quote the great Fred Hampton: "We don’t think you fight fire with fire best ; we think you fight fire with water best. We’re going to fight racism not with racism, but we’re going to fight with solidarity."
You don't fight fascism with anti-democratic tendencies (i.e. shutting down polling stations or making it harder for people to vote). You fight fascism by supporting working people across the country, supporting their right to organize, protest, strike, and education. You fight fascism not by quibbling about slogans, but by encouraging more BLM protests, the likes of which did more to save democracy than any Beltway liberal. You pack the court while also working to challenge the aristocratic privilege of the court itself, rejecting the power of 9, 11, or even 13 judges to decide the law of the land over and above the rights of the people.
In other words, you cannot do what the GOP has done 'more effectively' without also accelerating the trend arc toward fascism. There is another way.
