Politico makes the case against an Obama candidacy:

Far from a no-holds-barred affair, the Democratic contest has been an exercise in self-censorship.
Rip off the duct tape and here is what they would say: Obama has serious problems with Jewish voters (goodbye Florida), working-class whites (goodbye Ohio) and Hispanics (goodbye, New Mexico).
Republicans will also ruthlessly exploit openings that Clinton — in the genteel confines of an intraparty contest — never could. Top targets: Obama’s radioactive personal associations, his liberal ideology, his exotic life story, his coolly academic and elitist style.
This view has been an article of faith among Clinton advisers for months, but it got powerful new affirmation last week with Obama’s clumsy ruminations about why “bitter” small-town voters turn to guns and God.
There’s nothing to say that the Clintonites are right about Obama’s presumed vulnerabilities. But one argument seems indisputably true: Obama is on the brink of the Democratic nomination without having had to confront head-on the evidence about his general election challenges.

Stories about Obama’s Chicago associations with 1960s radicals Bernardine Dohrn and William Ayers landed with barely a ripple. So, too, did questions about whether he once backed a total ban on handguns (he says no but in a 1996 state legislative race his campaign filled out a questionnaire saying yes). Obama’s graceful handling of the Rev. Jeremiah Wright controversy may have turned that into a net positive against Clinton.

Joe Klein makes the counter-arguments for Obama. But you lefties probably figure you’ll win either way so why worry? McCain is old, he ticked off the conservatives, he actually takes a stand on the issues, he wants to continue fighting the jihadists, he won’t talk to Iran and he’ll support Israel. Who wants someone like that?
