<p>SAN FRANCISCO (AP) - Rep. Darrell Issa, who catapulted to fame and controversy after bankrolling the recall drive against Gov. Gray Davis, will not seek the Republican nomination to challenge Democratic Sen. Barbara Boxer, a spokesman said Tuesday.</p>
<p>"We had every reason to be certain that if Darrell had chosen to seek the nomination for senate, it would have been his for the asking," said Issa spokesman Jonathan Wilcox. "But he is very committed and determined in his congressional work and has found it to be a passion and a purpose."</p>
