On Capitol Hill, the full Senate is expected to vote as early as this week on the nomination of John Bolton to become ambassador to the United Nations. Ohio Republican George Voinovich has begun circulating a letter urging his colleagues to vote against Bolton. If five Republicans join Voinovich, Bolton’s confirmation would fail. In his letter Voinovich wrote “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.”
