The Tea Party Express has released a poll showing Christine O’Donnell within striking distance of Mike Castle in the U.S. Senate primary. From Talking Points Memo:
But according to the Tea Party Express, they’ve been made aware of “some shockingly good news” about the race. The group released yesterday a Tea Party Express commissioned a poll of GOP voters that shows 43.7% Castle-38% O’Donnell, suggesting the result means Castle “is on the verge of seeing his political career come to an end.”
I don’t see anything about the internals of the poll, so take it with a grain of salt. If this is accurate it could explain why Castle is reacting so vigorously – he’s under 50% and it shows a lot of undecideds.
