The claim by people like Paul Ryan that they want to save American taxpayers money is rendered unbelievable by the amount of cash that they send, in various ways, to other countries at the expense of American taxpayers.
Rand Paul is the only Republican Senator that I am aware of who has called out this obvious hypocrisy.
However, a lot of voters notice it, and it damages the Republican brand very severely.
A few billion here or there is nothing to compared to trillions in entitlements, and to a lesser extent, endless wars.
