Clinton campaign manager urges supporters in an e-mail to "Come on in."

Hillary needs your help, and so do I. With just two days left until the Pennsylvania primary and races across the country following soon after, it's an all-hands-on deck moment here at national headquarters in Arlington.

We need as many volunteers as we can fit through the doors every day to make calls into primary states. The calls our volunteers make are a critical part of our plan for victory.

Sign up today to volunteer at campaign headquarters.

I can't overstate what a difference it means to this campaign to have Hillary's best supporters -- people just like you -- making calls and talking directly to voters. To put it as simply as I can, more calls equal more votes.

Even if you can only spare a couple of hours, you can have a big impact. Our calling system is so efficient that one person can make dozens of calls in a very short time. With a full phone bank, we can make thousands of calls per hour into the primary states.

The Pennsylvania primary is almost upon us. Hillary needs you.

Sign up for a volunteer shift.

I really enjoy meeting our volunteers and talking to them about why they're supporting Hillary. I hope I get to see you in the office soon

Sincerely,
Maggie Williams
Campaign Manager
Hillary Clinton for President
