Simple. Because the Big Donors don't "match well with the party", either.
In their view, the "base" is a mob of Bible-thumping, gun-toting redneck hicks.
It explains why they're so anxious for amnesty -- they want a more civilized class of voters.
I think the explanation is that the big donors have to “pay to play” anyway so they figure they mught as well pick the candidate.
Obviously we’ll know we’ve won the war against the GOPe when the Party tells them: “If you don’t ‘pay to play’ and support whatever candidates our people nominate... well, you know what happens to those who don’t pay.”
If we ever win that war. The big donors are now dependent on subsidized consumer spending- which is the antithesis of Conservatism and is unsustainable besides.
