Interesting look at McCain’s sometimes rocky relationship with his fellow Republicans by Paul Kane at the Washington Post.

John McCain once testified under oath that a Senate colleague inappropriately used tobacco corporation donations to sway votes on legislation. He cursed out another colleague in front of 20 senators and staff members, questioning the senator’s grip on immigration legislation. And, on the Senate floor, McCain (R-Ariz.) accused another colleague of “egregious behavior” for helping a defense contractor in a move he said resembled “corporate scandals.”

And those were just the Republicans.

In a chamber once known for cordiality if not outright gentility, McCain has battled his fellow senators for more than two decades in a fashion that has been forceful and sometimes personal. Now, with the conservative maverick on the brink of securing his party’s presidential nomination, McCain’s Republican colleagues are grappling with the idea of him at the top of their ticket.
