One the eve of the Republican National Convention, Massachusetts voters prefer their home state Senator over President Bush by a 58% to 36% margin.

Four years ago, without the home state advantage, Al Gore defeated Bush in Massachusetts 60% to 33%. Our last Bay State survey, released just prior to the Democratic National Convention, showed Kerry with a 60% to 31% lead.

Massachusetts remains safely in the "Likely Kerry" category for our Electoral College projections.

Kerry leads among all age groups in Massachusetts but has his biggest advantage among those aged 50-64. Bush does best among 40-somethings, but still trails.

Just 40% of Massachusetts voters Approve of the way President Bush is performing his job. That's up three points from our last survey, but still well below his national Job Approval rating.

Overall, 60% of Massachusetts voters disapprove of the President's job performance, including 47% who strongly disapprove.
