“As he has promised to do for months...”
Exactly. Meaning, the GOPe had months to prepare an immediate and definitive response to the wannabe emperor.
The only immediate was the whine. The only thing definitive was the cowardice at responding to a Constitutional crisis.
However you can argue that there is no crisis as the GOPe actually supports the Regime's actions. The GOPe wanted amnesty, but now they have got what they wanted without having to take a stand by actually voting for it. The GOPe can pander to conservatives with their whining, while patting themselves on the back for their good fortune.
