More on Muhlenberg / Morning Call Poll

Some more details are out on the Morning Call / Muhlenberg Poll at Mcall.com.

The latest poll reflects a consistent narrowing of the Santorum/Casey matchup. Two months ago, Casey enjoyed a 16-point edge, but that's been eroding week by week. It fell to single-digits in polls taken earlier this month. A Zogby International survey released March 30 put the margin at 8 points; an April 5 Rasmussen Reports poll had it at 9 points.

According to Muhlenberg polling director Christopher Borick, the erosion of Casey's lead is tied to third-party campaign advertisements taking the Democratic state treasurer to task for his allegedly spotty job attendance.

A Virginia group called Americans for Job Security has spent more than $1 million on ads charging that Casey has missed work ''more than 43 percent of the time'' and was looking for a new job just three months after being sworn in as state treasurer. Casey's representatives have dismissed the spots as mud-slinging.

Calling the ads ''classic image attacks,'' Borick said they have moved voters who might have been in Casey's corner into the undecided category.

How many places have those ads run in? Was it really that many? (I'm going to find out).

The YCOP PAC also ran ads... which ran in the northeast part of the state.

Friend of SantorumBlog, Tim Chapman sums it up.

This past track record combined with this early movement in the polls has to scare the daylights out of the Casey campaign. Santorum has not even begun to spend money on ads yet. If Casey continues losing ground before Santorum goes on the air, he is toast.

Neither ad run made an impression on Tim... but I think he's in D.C.

In anycase, the race is tightening, as many (most) people have been saying.
