From Eric Dondero:

Delaware has a nomination process similar to Utah. Candidates are nominated at convention, but there is also a primary in September. Michael Castle easily won the Republican nomination in convention, and is the likely GOP nominee for US Senate. However, Christine O'Donnell is still running an active campaign for the primary. It is still possible that she could beat Castle in September.

O'Donnell is considered the hard-right candidate; Castle, more moderate. But interestingly, he happens to be the great, great, grandson of Benjamin Franklin (direct descendent).

This item from Will McVay, Libertarian for State Rep. DE 32nd District campaign blog:

Continuing the recent trend, the turnout at the Kent County [Central Delaware] Libertarian Party meeting for June grew from our May total of around 20 people to more than 30...

Christine O'Donnell, a candidate for the Republican nomination to the US Senate was also present and offered her views on the current state of our country and the steps she believes are necessary to remedy them. While she was eager to appeal to those in attendance currently registered in the Republican Party, she was also respectful of the Libertarian Party's candidate for US Senate, Jim Rash.
