Every Republican senator and virtually every representative challenged in a primary as insufficiently conservative will win. In reaction to ObamaCare, GOP political divisions are giving way to unity. Tens of millions more Americans will lose their coverage and find that new ObamaCare plans have higher premiums, larger deductibles and fewer doctors. Enrollment numbers will be smaller than projected and budget outlays will be higher. The White House will blame insurers and Republicans for the law’s continuing failures.

At year’s end, Kathleen Sebelius will still be HHS Secretary. Support for ObamaCare will drop below 30%, causing congressional Democrats to clamber for major changes and delays. The administration will resist most such ideas, except lifting the individual mandate penalty for 2014.

It won’t be all sweetness and light for the GOP, however. Republicans will debate joining rebellious Democrats in gutting and delaying elements of ObamaCare or leaving it alone.

The White House will be even more hard-edged and partisan— and not just because of John Podesta’s addition as counselor. Mr. Obama will do what he does when in trouble: attack. Expect more liberals to blame criticism of his actions on racism. The president’s willingness to ignore or unilaterally alter provisions of laws on the statute books—otherwise known as lawlessness—will be challenged by a growing number of successful lawsuits.
