What do voters want Members of Congress who approach every issue as if it were an ideological litmus test that reflects the ultimate battle of good versus evil, or Members with the experiences and character to bring less rigid perspectives and problem-solving skills to almost any issue?
Former Rep. J.D. Hayworths primary challenge to Sen. John McCain (R-Ariz.) is an obvious test case, much as Ned Lamonts challenge to Connecticut Sen. Joe Lieberman (ID) was in 2006.
Hayworth is running an issue-oriented, purely ideological challenge to McCain, arguing that the four-term Republican Senators voting record is wrong on taxes, bailouts, amnesty for illegal aliens, the federal marriage amendment, cap-and-trade, campaign finance and terrorism.
On his Web site, Hayworth, who is described as the consistent conservative, says that he would have voted differently than McCain on all these high-profile issues, as well as on the confirmation of Eric Holder as attorney general.
McCain, of course, calls himself a conservative and has a case to make.
McCains CQ Party Unity score for 2009 was 96 percent, the same score as Sen. Jeff Sessions (R-Ala.) and National Republican Senatorial Committee Chairman John Cornyn (Texas). Even Hayworth isnt likely to dismiss Cornyn and Sessions as moderates.
Admittedly, many votes are relatively noncontroversial, party-line votes, so a high party unity score doesnt mean that a Member might not have defected from the partys orthodoxy on a number of high-profile issues. And McCains party unity scores have been much lower: 93 percent in 2008, 76 percent in 2006, 86 percent in 2003 and 67 percent in 2001, for example.
But the Arizona Republican has the support of conservative darling Sarah Palin, and newly elected Sen. Scott Brown (R-Mass.), who has come to symbolize to many both the energy of the tea party movement and opposition to President Barack Obama, is traveling to Arizona on McCains behalf.
Even more important, McCain has spent years establishing a reputation for fiscal responsibility, particularly in his opposition to pork-barrel spending and the deficit. McCain voted in 2003 against final passage of the now-unpopular bill creating a new prescription drug benefit, calling it fiscally irresponsible. Hayworth supported passage of that legislation.
McCains record on spending is sure to resonate with Republican voters in Arizona. And this year, fiscal restraint will be a huge issue with GOP primary voters.
Of course, its also true that McCain is not as conservative as Hayworth.
McCains association with Sen. Russ Feingold (D-Wis.) on campaign finance and with the late Sen. Edward Kennedy (D-Mass.) on immigration reform sends some conservatives into a frenzy, as has his vocal opposition to enhanced interrogation techniques.
Hayworths 2004 scores (to pick a year when both Republicans were in Congress) from the AFL-CIO and the liberal Americans for Democratic Action, for example, were much lower than McCains, and Hayworths ratings that year from the U.S. Chamber of Commerce and the American Conservative Union were much higher than McCains.
