I didn't say that Obama won michigan or florida. I just said that had he been allowed to campaign/ visit those areas, his vote numbers would have carried him over in the popular vote IMO. Also, the Texas caucus voters probably were voters in the primary as well. However, the way the Texas system is set up, their votes can count twice, and since Obama destroyed Hillary in the caucus, I'd be banking the the number Obama voters there was significant enough to make an argument for coming close to or surpassing Clinton's vote total.
As we have learned 8 years ago, you do not even need to win the popular vote to become pres.
Also, yes the DNC encouraged candidates to pull themselves off the Michigan ballot, with the Keebler elf aka Kucinich unsuccessfully attempting to do so. However, I do agree that Gravel and others should have been invited to more debates. Though Obama got a lot of attention, I think he deserved a lot of it as he won 12 straight primaries and won some early crucial states.
