It's important because some people have such bad tunnel-vision, they only vote exclusively for whichever party. They don't care about the issues, they defer to the candidate that has the right letter next to their name.
SDadnly enough, this country is divided into two parties, both of which ignore the will of the populace pretty evenly. They make it a big deal to vote for one party or the other and make it a priority to squash other parties so that the R's and D's cafn keep holding onto their stranglehold of power.
