Can Trump actually cancel federal elections?

I have done some research but really want to know if I’m missing something. First there is no valid mechanism that give the president the ability to cancel midterms or any federal election. Not invoking the insurrection act … not declaring martial law … nothing.

Notwithstanding I have no doubt he will unilaterally try anything to do so. If, hypothetically, he was able to prevent the midterm (which are totally under each individual state’s control) ALL house seats would become vacant on January 1 … no house at all. No federal funding … nothing. Everything just stops.

Looking at the senate 33 seats are up in the midterms. 20 R and 13 D. Those seats will disappear. The remaining senators can form a quorum but the balance of power would shift to the Ds

Biggest question is why any sane republican politician would ever want this?
