This prophecy talks about the rise of a powerful third party in American politics. This new political party will be a unified party, a Godly party, and one that is very strong in faith, resilience, and power, and which will push the Democrats, the Republicans, and pretty much everyone else aside. Given recent information I've come across, I believe this party won't appear until the great super revival, that's coming soon, has gotten off the ground, as it will grow out of that revival.
EDIT (2021-05-02): Given recent information I've just come across, I've come to realize that the party being talked about here hasn't appeared yet. A few possible replacements have shown up, but apparently not the one God has in mind.
