Agreed. However, unless THIS Congress delivers a confirmation on Alito, and something substantive and immediate on illegal immigration before the mid-terms, I'll never donate again. This Back-of-the-Bus Republican has had it.
My view on the GOP, which I share with other conservatives, is:
"Don't leave: take over."
In the meantime, always a good idea to indulge innate distrust of redistribution of your money by a centralized committee, namely the RNC. Plus, giving directly to candidates/causes gives you more of a say.
