At a time when polls show public opinion turning against the Democrats, some Republicans seem to be turning against each other. Even with the prospect of being able to win control of the Senate in this fall's elections, some Republicans are busy manufacturing ammunition for their own circular firing squad.
A Republican faction's demonization of their own Senate Minority Leader, Mitch McConnell, is a classic example. If you listen to some of those who consider themselves the only true conservatives, you would never guess that Senator McConnell received a lifetime 90 percent ranking by the American Conservative Union -- and in one recent year had a 100 percent ranking.
Ann Coulter -- whose conservative credentials nobody has ever challenged -- points out in her column that Mitch McConnell has not only led the fight for conservative principles repeatedly, but has been to the right of Ted Cruz on immigration issues.
Someone once said that, in a war, truth is the first casualty. That seems to be the case for some in this internal war among Republicans. As the late Daniel Patrick Moynihan said, "You are entitled to your own opinion, but not to your own facts."
Why should those of us who are not Republicans be concerned about any of this?
Fortunately or unfortunately, we have a two-party system in this country. And -- very unfortunately -- we are at a crucial point in the history of America, and perhaps approaching a point of no return.
The unfolding disaster of ObamaCare is only the most visible symptom of a far deeper danger from a lawless administration in Washington that unilaterally changes laws passed by Congress. President Obama has nearly three more years to continue doing irreparable damage to the fundamental basis of American government and Americans' freedom.
Only Republican control of the Senate can rein in the lawless Obama administration, which can otherwise load up the federal courts with lawless judges, who will be dismantling the rule of law and destroying the rights of the people, for decades after Barack Obama himself is long gone from the White House.
Once that happens, even a future Republican majority, led by people with the kind of ideological purity that the Republican dissidents want, cannot undo the damage.
The Senate's power to confirm or not confirm presidential nominees to the federal courts is the only thing that can prevent Barack Obama from leaving that kind of toxic legacy in the federal courts, including the Supreme Court.
