The problem is not conservatives who will vote Trump no matter what, liberals who will vote Biden no matter what. It's racist suburbanite independents who are racist against Hispanics. (I don't call them Latinx or Latino because Hispanics don't want to be called that according to polling)
It's because of these racist pseudo centrists we have this problem. Due to suburbanites from Texas, Georgia, Ohio, and Arizona being somewhat racist is why we have to fear immigration from Hispanic countries. Real centrist is cosmopolitans that agree with immigration-friendly liberals, progressives, social democrats, and the broader left.
You guys may hate Manchin, but his voters will vote Republican no matter what.
Biden is not a racist immigrant hater, and Harris isn't either but Sinema's voters are somewhat like this.
These people are greedy, short-sighted, and dangerous to the continuation of America as a world power, and to the very essence of the American dream.
