The Squad faces a series of tests in primaries

This week symbolised the absolutely shambolic state of Republican infighting. On Monday, Donald Trump threw a grenade by impying that he simply would leave states to decide abortion — while not explicitly saying whether he would veto an abortion ban, just that he would not sign one.

Then, on Wednesday, the House Republican conference once again soiled itself when it voted down a rule to begin debate on reauthorising the Foreign Intelligence Surveillance Act.

But these internecine dealings are not so much about policy as they are about tactics. On Friday, the House passed a new version of the rule after. And even if not all Republican Senators want to take up impeaching Homeland Security Secretary Alejandro Mayorkas, they most certainly want to continue to make immigration the defining issue of the 2024 campaign.
