If you are a "normal" conservative, you can vote for the "normal" conservative in the primary. And there are plenty of places where most conservatives are "normal" conservatives, like New Hampshire and Maine. They tend to elect "normal" Republicans to office, like Sununu and Collins.
Whereas places where most conservatives are MAGA, like Florida, tend to elect MAGA Republicans to office, like Gaetz. When "normal" conservatives run in Florida primaries, you can vote for them but they will lose.
So it's not true that "There is no conservative without that nazi bullshit". In fact, if you wanted a non-MAGA conservative president, you could have voted for Nikki Haley. But she was ultimately eliminated by MAGA voters.
There are many more like her in power elsewhere in government. Unfortunately they are mostly cowards (like Haley herself), and prefer to remain silent than to challenge MAGA in public.
