With President Bush's approval numbers falling to new lows in all recent polls, Mystery Pollster notes we need to consider Bush's support among Republicans to see if they can go much lower. "The overwhelming majority of those that now approve of his performance are either identify as Republicans or tell pollsters they are independents who 'lean' Republican (see the IPSOS crosstabs). For Bush's numbers to fall much further, he will need to lose significant support from Republicans."
"So far, at least, any such erosion has been minimal." In six recent national polls, Bush "shows an average 80% support from Republicans across the six surveys. " And in the two polls that indicate trends, "both indicate that for now at least, Bush's support from Republicans is holding at roughly 80%."
