Vice President Joe Biden sent this message today, inviting people to President Obama’s birthday party in Chicago:

Barack's turning 51 in a couple weeks. And when he goes home to Chicago for a birthday party in his backyard, a couple grassroots supporters like you will be flown in from wherever you live to celebrate.

In the middle of a tough election, it's important to pause on occasion and take some time with friends.

What do you say?

We'll cover the flight and hotel for you and a guest—make a donation of any amount to be automatically entered to win.

Take it from me. You'll have fun at this one.

Joe
