have it , Ann Coulter suggested donors hold on to their cash . And so, although if Mr. Romney had picked Mr. Ryan a few weeks ago, there surely would have been cheers in the GOP cheering section, now he almost has to pick him just to quell the nascent revolt. There is only one problem: Picking Paul Ryan to be his running mate would be an unmitigated disaster. Already, Democrats have made Mr. Ryan's calling card -- the Ryan Budget, with its deep cuts to entitlement programs, into an epithet. After Mr. Romney called the budget "marvelous," Mr. Obama mocked him for it. For the GOP base, the list of things they are willing to forgive Mr. Romney over is long -- earlier waffling on abortion rights, the health care mandate, a certain lack of NASCAR cred. On each, Mr. Romney disappoints. Picking Paul Ryan would endear him to many on the right, but with the great risk of giving him campaign an extra burden.
