Insurgent Republican Wins in Delaware
By JEFF ZELENY
The Tea Party movement scored another victory on Tuesday, helping to propel a dissident Republican, Christine O’Donnell, to an upset win over Representative Michael N. Castle in the race for the United States Senate nomination in Delaware.
Mr. Castle, a moderate Republican who served two terms as governor and had been reliably winning elections for the last four decades, became the latest establishment Republican casualty of the primary election season. Republican leaders said the victory by Ms. O’Donnell complicated the party’s chances of winning control of the Senate.
And in New York, a Tea Party-backed candidate, Carl P. Paladino, appeared poised to defeat former Congressman Rick Lazio, a favorite of Republican party leaders, in the primary for Governor. A Palidino victory could send shock waves through the New York Republican Party as it prepares to do battle with Andrew M. Cuomo in the November elections.
