Sure, I'll agree with that. Showing up is way better in all regards of democracy. But, most folks (90 percent of voters lets say) still won't be bothered.
But, of course everyone that voted to have the caucuses will show up, so we tend to have a holier than though attitude about this kind of stuff.
Fuse Washington shows exactly how holier than though. They put together a list of all the reasons someone can't attend a caucus. Of course they forget about "I have to work," but they bother to put in my wife's reason for not going:
I don't have childcareMy son will be napping throughout the caucus process, so we're under no circumstances bringing him to a crowded room full of excited Democrats. And, if we did have childcare, who do you think is providing that childcare?
Bring the kids with you! Anyone can attend the caucus (although you have to be 18 years old by election day to particpate). Then you can make them write a paper on the democratic process.
Someone shut out of the caucus.
