Here’s how President Barack Obama‘s reelection campaign is expanding its profile of supporters to hit up for cash:

On the site BarackObama.com, there’s a men’s college basketball bracket challenge. Visitors can fill out their picks and the site will publish those who do better than Obama’s own picks once the tournament is over.

Here’s the catch:

To participate, users must provide their full name, email address and ZIP code.  They’re also prompted to make a donation to the campaign after submitting their picks.

Obama hasn’t filled out his own bracket yet. He usually does so in March in an interview with ESPN’s Andy Katz.
