When exactly is Trump going to become president of the United States? After 2020? We don't have time for the training wheels to come off.
Maybe Trump's policy failures on immigration are HIS FAULT. Blaming Obama holdovers is ridiculous when Bush 41 cleaned house on accession by firing all the Reagan administration holdovers OVERNIGHT.
This reminds me of nothing so much as the Limbaugh Theorem, not holding the president accountable for his own policies, except now Republicans are doing it.
Trump is doing nothing because that's the way he wants it. It's politics, not policy, and for playing politics with the nation's integrity and security, for that alone he shouldn't be president right now, let alone in 2020.
Trump is every bit the scoundrel now his past life says he always was.
