It won’t be when more and more democrat crimes get exposed before then.
I am betting that POTUS works to have charges brought against several democrats just before the mid-terms. That would be a sweet October surprise.
Indictments of Deep State miscreants could be a major influence on the election. Or, Trump might pull off a major accomplishment like a tariff and trade deal, or a nuclear arms agreement with Russia, or get North Korea to deliver on denuclearization in a big way. One of the advantages of being the party in power is to have the ability to deliver successes that can alter the outcome of an election.
