I don't recall a 'Support Clinton' line. That was a while ago, though. They had the Republican/Democrat lines back when Clinton was in office if I remember correctly. CSPAN doesn't like to talk about the phone number issue. Callers bring it up occasionally and they ignore the question and go on to the next caller. .
I do give CSPAN some credit for airing the demonstrations in NY in 2004 regarding the war in Iraq. They were about the only network that covered it. All the other corporate networks ignored it. Fox broke in for a minute when the dragon caught fire right next to McDonald's. We need some networks that give the common people a chance to talk, instead of the same old corporate cronies from Newsweek, Time, the White House, etc. We could have a great reality show that goes around the country and covers demonstrations. But no network has the guts to do it. They're afraid of what might happen if people actually start thinking for themselves and became activists. .
