// The us_presidential_frontrunners module is trying to present an external
|
|
// interface (the `democrat` and `republican` constants) that is different than
|
|
// its internal structure (the `democrats` and `republicans` modules and
|
|
// associated constants). It's almost there except for one keyword missing for
|
|
// each constant.
