After President Obama filled out a NCAA bracket on ESPN, Nebraska Senate candidate Ben Sasse is poking him for his "Constitutional Madness."

Sasse asked his fans to choose Obama's worst constitutional violation, such as "forcing taxpayers to violate religious conscience by funding abortion through Obamacare" and "Using the IRS to suppress Tea Party free speech."

The site is sufficiently wonky, but it only lets users pick the first round of the bracket before asking for their email.

We're not sure which item is leading at the moment.
