Any white identitarian will tell you the existing power structure is designed to keep a white identitarian out of power. In the short run they can “hide their power level,” but that requires discretion and risk taking. In the long run, White identity politics will be more than elections and polls.
Most whites vote Republican and the vast majority of Republicans are white. That means even though White people right now don’t all share GOP/conservative values, but most of your conservatives will be white. The PoC identify conservatism with whiteness and whiteness with their oppression. Think about what you are “conserving” in the eyes of these racialist non whites. Americana is akin to Nazi imagery to them and the Founding Fathers are the NSDAP. It isn’t helped by the fact that the Founders were literally racist. Not “Asians are bad drivers” racist but, “the negros are intellectually and morally inferior” level racist. Any loyalty or admiration you have for them is racist. All attempts at retconning history to make the Founders out to be egalitarian or at least “tolerant” are easily debunked. All of this is the wedge.
As the racial electoral divide widens you will see GOP vs DNC turn into proxy White v PoC voting before it turns explicitly racial. Your “conservative” values will just be labeled White values. At this point they will functionally be White values because the PoC will use the power of the state to rob and disarm you. If there is no opposition to the PoC agenda, you will see the United States turn into Zimbabwe.
Back to elections, the aforementioned short run strategy is your best bet. How far you can go before going too far will be determined by the local electorate and your enemies on the national level. Once they have any power they will need to use every ounce of it to both reverse demographic trends and disenfranchise voter blocs that oppose them.
Lucky for us, the enemy broke many laws to acquire power. Mere enforcement of current law gives you a lot of power. Bill Clinton gave us the power to put physical barriers on the US-Mexico border and Trump is just following the law. Ethnic churches operate like political machines. It’s against federal election regulations for a preacher to endorse candidates from the pulpit. Take their tax exempt statues. Government employee unions provide campaign staff for the DNC at your expenses. Ronald Reagan and Scott Walker knew how to deal with those. Universities indoctrinate your children to hate you can and offer extra credit for students to campaign for the enemy. How long do you think they would last without state or federal grant money? You can run on a “conservative” platform for now, but in the end it’s the White platform.
This might seem pretty long for a short term strategy but the mess we are in took decades to get in; getting out without secession or civil war can take more than a century. You will need to overthrow the entire culture that brought us to this point. You had to have Freud before you had Free Love.
