Sometime on Thursday, as most of us now know, GOP presidential candidate John McCain stopped by D.C. in a now-rare appearance at the Capitol to help put the finishing touches on the immigration deal. Impatient with some of the final deliberations, he cursed at fellow Sen. John Cornyn, R-Texas.
Scott Johnson at Powerline has put together some context and background around what happened there. It has deep implications for those of us considering who can best lead the GOP in 2008. As Scott notes:
The eruption of Senator John McCain at fellow Republican Sen. John Cornyn (TX) is an incident that reverberates on several levels. It renews lingering doubts about whether Senator McCain possesses the proper temperament to be president. It also raises serious questions about the substance of the "grand bargain" immigration bill that Senators Kennedy, Specter, McCain and others are attempting to rush through the Senate.As to the substance, the problem is that Senator Cornyn was attempting to make sure there was an infrastructure to deal with those who didn't comply with the new immigration law. Kennedy said that was a deal breaker and McCain, impatient and with a flight to catch agreed and pushed on.
