You're making three completely different claims and treating them like one argument. Democrats voting in Republican primaries doesn't prove some coordinated master plan, and having ideological disagreements doesn't mean a political party has no identity. Every major political party has internal factions. Also, if your entire argument is that Democrats can't function without Trump, why does your supposed master plan require them to be so politically influential in the first place?
Basically, the plan is that democrats will gut the republican party down to the studs. Once the factions within it are no longer united by Trump, the party will go through long rough patch where they have enough candidates but no unity among the factions and no real message. Then they'll become the DSA, which a majority of americans don't support. Then, America First comes in to the empty republican party, rebuilds it as the pro-America partyโฆ
