Another Republican Breaks Ranks with Party Leaders

For the second time in as many days, a Republican senator has broken ranks with his president and leadership. Yesterday, seven Republican senators signed the compromise to avert a nuclear disaster in the Senate.

The NYTimes reports that Senator George R. Voinovich of Ohio did it again, sending a letter to his Republican colleagues urging them to vote against the confirmation of John Bolton to be the next US ambassador to the United Nations when his nomination comes to the floor of the Senate.

"In these dangerous times, we cannot afford to put at risk our nation's ability to successfully wage and win the war on terror with a controversial and ineffective ambassador to the United Nations," Mr. Voinovich wrote. He urged colleagues to "put aside our partisan agenda and let our consciences and our shared commitment to our nation's best interests guide us."

In addition to sending out his letter, Mr. Voinovich was also making telephone calls and meeting with other Republican senators to urge them to oppose Mr. Bolton's nomination, according to two Senate Republican officials.

With such a lack of party loyalty on display this week, are we seeing the beginning of the unraveling of the GOP Senate majority?
