Brace yourself for the invasion of the Clintons.

With just four weeks until Pennsylvania goes to the polls in the hotly contested Democratic Primary, members of the Clinton clan will be all over the Delaware Valley today.

But don’t get your hopes up, Delco. They’re skipping us this trip.

Former president Bill Clinton will get the party started this morning with a rally in Pottstown at the Pottstown Senior High gymnasium. From there he’ll shuttle over to Albright College in Reading. Then it’s off to Dickinson College in Carlisle.

Former first daughter Chelsea Clinton also will be doing some serious face time in the area. She’ll start her day at noon in Bensalem. At 3:30 she’ll host a rally at Sykes Student Union on the campus of West Chester University. Finally tonight she’ll look to wow the faithful at Cobre on North Broad Street in Philly.

A tip for those chatting up Chelsea. She doesn’t take kindly to any prying questions about Monica Lewinsky. One college-type recently asked her if she thought the L’Affaire Lewinsky damaged her mother’s credibility.

A clearly startled Chelsea responded it’s the first time in the 70-some campuses she’s visited that she’s ever been asked that question. Then she recovered and fired off the perfect response: It’s none of your business.

Good for her.

And that other guy, Barack Obama? He won’t be back in the state until tomorrow, when he’s planning to kick off a bus tour in the western part of the state before heading east.

We’ll let you know when one of the candidates makes the inevitable pit stop in Delco.
