Republicans have been accused of being the party of “no.” The idea is that being perceived as blocking rather than facilitating legislation is ordinarily an unpopular stance. But it could wind up being popular to say “no” to unpopular bills.
RINO Lindsay Graham appears to be the key figure in blocking both efforts, since he was previously the key “bipartisan” figure in support of both efforts. I do not trust him to maintain his opposition. But there is little question that, without the election of Scott Brown, the Democrats probably wouldn’t even need to court Graham’s favor at all; they could probably garner enough votes without him, as they did for HCR.
