how about:

```javascript
var report_types = [
    'Party going door-to-door',
    'Party intimidating voters',
    'Party distributing food/money/gift',
    'Campaign rally',
    'Campaign violence',
    'Protest/Demonstration'
]
```
and

```javascript
choices = report_types.map(function (description, index) {
    return new Choice(index + 1, description)
});
```

and `self.get_desc(content)` would be replaced with `report_types[choice - 1]`;
