Pat Toomey's campaign bus swings through Kittanning, Butler, Pittsburgh and Washington today, while Joe Sestak holds an "Education Crisis Panel" at the Gather the People House of Prayer in Philadelphia this afternoon.

The Politifact folks at the St. Pete Times studied one of the ads the Toomey camp released last month on Sestak (see them here) and estate taxes, and rated the GOPr's claims as "barely true." The whole column is worth reading but here's the summation:

To recap, while there is some truth to Toomey's claim because Sestak supports reviving the estate tax, Toomey exaggerates the scope of the tax, incorrectly implying that it would apply to far more taxpayers, and that it applies to their entire estates. In fact, only the wealthiest Americans would pay the tax under the proposal that Sestak supports, and the proposal would exclude $3.5 million per person and $7 million per couple. On balance, then, we rate the ad Barely True.
