It’s an internal poll, so take it with as many grains of salt as you deem necessary, but this is a pretty interesting indicator in Joe Sestak’s suburban Philadelphia district:

An internal poll from the Pat Meehan campaign obtained by PoliticsPA shows the Republican congressional candidate leading Democratic opponent Bryan Lentz by 21 points, 47 percent to 26 percent, largely on the strength of a nearly 2-to-1 advantage in name ID.

The poll, conducted by Fabrizio, McLaughlin and Associates, surveyed 400 “likely 2010 voters” from in the 7th Congressional District on June 16 and 17. The questions, provided in the polling memo, appear straight forward, and campaign officials say those surveyed were not read any information about the candidates before answering.

The matchup between Lentz and Meehan in the southeast district is arguably the state’s most competitive as both men try to take over the seat left by outgoing incumbent Democrat Joe Sestak. The Republican is generally seen as the favorite based on his local ties, fundraising and a favorable political climate, but no poll on the race had been publicly available until Tuesday.

Also, I think it’s time to retire this cliché:

“Bryan Lentz is focused on people — not polls,” said Lentz spokesperson Vincent Rongione, who until recently had been the candidate’s campaign manager.

Who, if not people, answer poll questions? House pets? Answering machines?
