So what? Senators and representatives are rarely in the news. I consider myself pretty well informed, and I can't name either of my senators or the representative for my district. If they asked about how they felt about significant policy initiatives in Washington (changes in rules for mortgage refinancing, tax code changes, the budget deal, etc.) you might have gotten a good idea of how informed the person was, but I guess the reporter would rather ask gotcha questions.
Not really. No.
If one doesn't even know their senators or rep they forfeit the right to have an opinion about politics IMHO. Willful ignorance is NOT to be tolerated when speaking about the future direction of our Nation (which the protesters are full of).
