What a jackass.

Via Politico:

Sen. John McCain (R-Ariz.) ripped fellow Republicans on Thursday for objecting to a package of aid and sanctions to respond to the Ukrainian crisis, calling himself “embarrassed” and telling his GOP colleagues: “Don’t call yourself Reagan Republicans.”

The Senate has erupted in a dispute over provisions related to the International Monetary Fund in the Ukraine bill, as conservative Republicans protest that it is an unnecessary component of the package that passed the Senate Foreign Relations Committee on a bipartisan vote this week.

In a fiery floor speech Thursday evening, McCain, who backed the Ukraine bill and has urged for a speedy congressional response, said he hasn’t “been embarrassed this way about members of my own party.”

“I will say to my friends who were objecting to this – and there are a number of them on my side – you can call yourself Republicans; that’s fine because that’s your voter registration,” McCain said. “Don’t call yourself Reagan Republicans. Ronald Reagan would never – would never – let this kind of aggression go unresponded to by the American people.”
