Thirty percent (30%) of conservative Democrats say they’re voting for John McCain. Rasmussen Reports data also shows the Republican hopeful picking up support from 19% of White Democrats and 15% of Democrats over the age of 50. These results are from national telephone survey interviews conducted with 14,000 Likely Voters during the two weeks ending July 24. The sample includes 5,074 Democratic voters.

The data shows that 43% of Democrats consider themselves politically liberal, 37% say they’re moderate, and 18% are conservative.

Forty-one percent (41%) of conservative Democrats have a favorable opinion of John McCain. Sixty-seven percent (67%) say the same about Obama.

Among liberal Democrats, just 23% have a positive opinion about McCain, but 90% give Obama favorable reviews.

Obama is supported by 78% of Democrats overall, a figure that includes 62% of conservative Democrats. He leads 84% to 13% among Democrats under 30. But, among those over 65, Obama earns just 74% of the vote while McCain is preferred by 16% of Democratic senior citizens. It is interesting to note that just 2% of Democrats under 30 hold back from selecting either Obama or McCain. That number grows to 9% among Democrats over 65.

While Obama is losing some Democratic voters, he begins with a significant advantage over McCain by virtue of the fact that there are far more Democrats in the country than Republicans.

Overall, there are twice as many uncommitted voters at this point in Election 2008 as there were four years ago. An analysis released yesterday showed that there are more Democrats than Republicans in the uncommitted category, but that they are leaning more towards McCain than Obama.

The Rasmussen Reports daily Presidential Tracking Poll shows that the race between Obama and McCain remains competitive. Other key stats of Election 2008 are updated daily at Obama-McCain: By the Numbers.
