"Rasmussen Markets data gives Democrats a 61.5% chance of winning in November (results are updated on a 24/7 basis by market participants).
" The Rasmussen Reports Balance of Power Calculator shows Democrats leading in states with 200 Electoral Votes while the GOP has the advantage in states with 189"
"Senate polling shows at least ten Republican Senate seats could be in play for Democrats during Election 2008. These include Senate seats in North Carolina, Oregon, New Hampshire, New Mexico, Colorado, Alaska, Minnesota, Kentucky, Virginia, and Texas. Underlying this dismal outlook for the GOP is the fact that more and more people are considering themselves to be Democrats. In fact, the Democrats now have the largest partisan advantage over the Republicans since Rasmussen Reports began tracking this data on a monthly basis nearly six years ago. "
