Primary elections and caucus meetings are radically different from the general election. Obama isn't just going to win because he converts Republicans, he will win if Democratic turnout is big and Republicans stay home. That's about it.
With McCain running, its entirely possible. The religious right isn't inspired by McCain because he's been anti-religious right in the past (at least in rhetoric).
If you want to see what is disturbing about Obama right now, if the primary elections can tell us anything, its that Obama didn't concisely win Missouri. Missouri may be a run-of-the-mill American state with nothing special to talk about, but its a bellweather state that has voted with the Presidential winner for many generations. They voted Bush, Clinton, Bush I, Reagan, Carter, etc... Go back for 100 years.
Its a KEY battleground state that must be won.

That's the 2008 Democratic Primary official results. Obama didn't win any counties outside the urban areas of St Louis, Kansas City, the college town and capitol city of Columbia and Jefferson City in the central part of the state, as well as one small county in the northwest of the state.
Obama won the core urban vote and absolutely nothing else. THESE AREAS WILL ALREADY VOTE DEMOCRAT regardless who is running, and Hillary stands a better chance at winning overall in a GENERAL ELECTION when millions more voters will be coming to the polls.
This is horrible news for Obama and a horrible sign for the general election. If he can't inspire more than the bare Democratic base to vote for him in a primary, how does this bode for a general election? Remember, most people voting in the primary are party activists, and Obama only won the urban vote which is going to be voting Democrat anyway come fall.
Leaves a lot to think about.
A lot of these states where Obama is winning 60% of the vote, like South Carolina or Nebraska or Idaho, are so strongly Republican in a general election we already know he can't win there. His wins are highly misleading because these are primary voters where mainly Democratic party members are a part of.
While he has plenty of time throughout the rest of the year to build a coalition, I fear Obama isn't as electable as current national polls suggest. Its why I've been a Hillary supporter.
But if he's the nominee, I hope he wins and I hope he pulls off a convincing victory. The nation can't stand another Republican administration right now, doesn't matter how "moderate" McCain says he is or the fact that he has a few moderate leanings in the past. He's still more of the same: pro-war, pro-wealthy class. He's not into programs to help the middle class at all, in fact he's a traditional conservative more-so than Bush on domestic programs, and he's just as pro-war as Bush is.
Its a dangerous mix. McCain is simply bad, bad, BAD.
