"I think", so your source for your claim that Nick Fuentes has the most popular podcast is basically "trust me bro"? Speaking of stupid...
Now let's look at the facts:
The majority of Republicans are over the age of 50, the Republican base is mostly boomers and early GenXers (but Pickles insist these 50+ year olds are all listening to Nick Fuentes.) Even the majority of 40 years olds (late GenXers, 47%) are mostly Republicans. These are all people who experienced Desert Storm and/or the War on Terror as adults, so unlike clueless zoomers and Alphas who think the ME is #FreePalestine, these boomers and GenXers have no delusions about the ME, who runs the show there and how, and what is at stake for the US.
The Democratic Party holds a substantial edge among younger registered voters – a pattern that has been in place for more than a decade.

Gen Z and Gen Alpha are not significant enough in terms of absolute numbers for Republicans to worry about whomever they're listening to. Nick Fuentes insisting that he's the one delivering a big chuck of zoomers or Alphas to either the Republicans or the Democrats making a difference in elections is just another example of his megalomania.
You forgot to say
"I think".
