John F. Kennedy wrote a Pulitzer Prize-winning book in the 1950s titled Profiles in Courage. Bill Clinton in 1992 had an incident called his “Sister Souljah moment” — a phrase that has become synonymous with the same definition of political courage used by then-Sen. Kennedy in his famous work: the willingness to stand up to your own base when you feel it is the right thing to do, even though it might be the hardest thing to do.

On the merits, I strongly disagree with extending any of the Bush tax cuts — disagreeing with President Obama and most Democrats that the middle-class cuts should be extended. I am concerned that by extending all the Bush cuts, we are adding another $3 trillion or more to the national debt, leaving our grandchildren and probably our great-grandchildren (I should live so long) to pay the tab.

I would have preferred allowing the Bush tax cuts to expire and reverting to the tax rates and policies that existed under President Clinton. As I recall, Clinton ended his second term after an era of unparalleled prosperity, having created more than 23 million new jobs and converted a $300 billion deficit at the beginning of his first term into a $1 trillion surplus by the end of his second (with a 65 percent job approval rating, by the way).

Instead, thanks in part to the Bush tax cuts (and, to be accurate, also because of 9/11 and many other factors), Democrats and Republicans spent eight years using credit cards to pay for two wars and a multitude of social programs (also, to be fair, programs that we liberals supported without being willing to pay for them). It is accurate to say that we decided to borrow from the Chinese government to pay for our current expenses, including allowing multimillionaires (and most of the rest of us) to pay less in taxes.

But given the slow recovery from the Great Recession of 2008-09, I can understand the reluctance of most Democrats, including President Obama, to allow the higher middle-class paychecks derived from the Bush cuts to expire amid what appears to be a slow but steady economic recovery.

So I didn’t get my way when the president chose to compromise.

But then again, I recognize that we lost the November elections because there aren’t enough Americans who vote who agree with my liberal views. So I don’t end up with saying to President Obama, “My way or the highway.” The reason, for me, is simple: I am not one of the unemployed whose compensation will now be renewed for a year thanks to President Obama’s willingness to compromise and take the heat from his liberal base.

So I ask my fellow liberals (and in particular, the brilliant liberal New York Times columnist, Frank Rich, who wrote quite an ugly personal attack on President Obama this past Sunday for his apparent willingness to compromise with Republicans on the cuts, among other issues):

Would you prefer no deal at all (and thus, no extension of unemployment compensation) if you were unemployed and your unemployment payments were about to run out just before Christmas?

Or to put it another way, do you believe there is a single unemployed person whose unemployment payments would cease who opposes President Obama’s compromise agreement with the Republicans?

I don’t think so. Do you?

So while I disagree with the extension of these tax cuts, especially to those in the highest income brackets, I appreciate the willingness of President Obama to take the heat from his own political base — knowing the larger good to the middle class to avoid paying higher taxes and to the unemployed to enjoy continued benefits.

In the final analysis, elections are won between the 20-yard lines. Only a wealthy purist liberal has the luxury of preferring to just say no rather than accepting incremental progress through compromise, as President Obama showed the profile in courage to do.
