Delaware Republican Primary Poll Christine O'Donnell leads Mike Castle 47-44

Delaware Senate Primary Too Close to Call

Raleigh, N.C. – It looks like there’s a real possibility of a major upset in the Delaware Senate primary on Tuesday night, with insurgent conservative Christine O’Donnell leading longtime Congressman and Governor Mike Castle 47-44. That 3 point lead is well within the poll’s margin of error.

If Castle is indeed defeated Tuesday night it will be yet another sign that conservatives have a strangle hold on the Republican Party and moderates may or may not be welcome anymore. Castle has an overwhelming 69-21 lead with moderate voters but they only make up 33% of the likely primary electorate. O’Donnell has a 62-31 lead with conservatives that’s more than enough to propel her to the overall lead.

It’s clear that Castle’s popularity has taken a sharp turn in the wrong direction over the last month. An August PPP poll found his favorability with Delaware Republicans at a 60/25 spread. Now his favorables within the party are negative at 43/47. That’s largely a product of 55% of voters in his party saying they think he’s too liberal compared to 37% who think he’s about right.

GOP voters are pretty sharply divided about O’Donnell as well. 45% have a favorable
opinion of her with 41% seeing her unfavorably. Only 50% of primary voters think she’s fit to hold public office but she does much better than Castle on the ideology front- 53% think she’s about right.

If O’Donnell pulls it out Tuesday night it will be a major victory for Delaware’s small but united group of Tea Party voters. Just 25% of Republicans in the state consider themselves to be members of that movement but they give her a 79-18 advantage that’s more than enough to overcome her 52-39 deficit with everyone else.

“The biggest winner of the Delaware GOP primary may end up being Chris Coons,” said
Dean Debnam, President of Public Policy Polling. “Running against O’Donnell or a
wounded Castle will put him in his strongest position since he entered the race.”

PPP surveyed 668 likely Republican primary voters on September 11th and 12th. The
margin of error is +/-3.8%. Other factors, such as refusal to be interviewed and
weighting, may introduce additional error that is more difficult to quantify.
