All the major Dem candidates are of the extreme-left variety. Corporations are always the bad guys, nationalize more and more of the economy, raise taxes, more govt control, judges who make up laws as they go, etc. They also want to appease our enemies in war and open our borders in various large degrees, which isn't particularly leftist but merely insane. In the past, whenever the Dems ran a candidate who was that far left, he's gotten creamed (see McGovern, Jimmah, Mondale). Even when they ran against a Republican who was moderately liberal, they still lost (see Gore, Kerry). The only Democrat to win in the last few generations pretended to be a "moderate" (Clinton), and even he never got a majority of the vote, despite running against candidates not very far to the right of his own feigned position. Obama, Hillary, and Edwards are all of the McGovern mold of modern extreme leftist. As such, they're already in trouble. But Obama has one thing the others don't, obviously: He's black. Racism is mostly gone in this country... but not completely. And in the November election, the nominee from each party obviously needs huge numbers of votes from the people in their own party, plus a hefty share of the "independent" vote. That wouldn't be a problem if the Republican nominee were black. But the Democrat party is the party of racism, going back even before the Civil war - an attitude that has not gone away even today. This is the party who continuously proclaims that minorities - and blacks as a group in particular - cannot make it without government help. And while saying this, they make no such claim about whites as a group. Bu they continuously push programs that keep blacks subservient and dependent on government, even while instructing them that they, the Democrats, will somehow "help" them with those programs. Many Democrats would undoubtedly vote for Obama anyway. Racism in the Democrat paty is not as pervasive as it once was. But it is not gone. There is still enough left to sustain the attitude that blacks are inferior to whites economically. And this will sadly remove some Democrat votes from Obama's column, that he would have gotten if he were not black. And given his extreme leftism, he doesn't have votes to spare. Personally I doubt that Obama's skin color will be the deciding factor in November, were he to become the Dem nominee. I believe his extreme leftist leanings will lose him so many votes (mostly from independents), that whatever more he loses to the racists and bigots in his own party, will be irrelevant. But even if the "independents" have moved so far to the left (see Lieberman) that he gets substantial votes from them, his color may alienate enough Democrat votes to become the straw that breaks the camel's back. We'll see in November, in the event that Obama gets the Dem nomination. Of course, no Democrat will tell any pollster that he voted against Obama (or stayed home) because of Obama's skin color. If the Dems have learned nothing else in the last fifty years, they've learned not to tell the truth about what they really want. Any of the top three Dem candidates will be in trouble in November, simply due to their McGovern-like leftist extremism and military confusion. But the last thing any of them needs, is to lose votes from their constituents who otherwise would have accepted their leftism.
