There are some undertones to this question that I'm not comfortable with and two important questions the post doesn't address, so I'm asking you to please clarify:

1. Why is "white people" important to the question?
2. Shape the future of America how?

Mod Note: Gave OP 15 minutes to clarify. Locking post due to the above unresolved questions and uncomfortable undertones in the nature of the post plus falling under Rule 2.

Considering that at least 2/3rds of all voters in the US are white I’d say so. But I’d also say that white voters already are the main force in shaping US politics, considering that they make up the majority of both parties as well.

Nonwhite voters can only sway things are the margins within the context of platforms that are acceptable to white voters. A candidate or platform that fails to garner white support is a political dead end, excepting a small number of local politicians.

This has been the (sometimes not so) unspoken platform of the GOP for a while now, so, I'd say yes
