Edwards finally faces up to reality

John Edwards will drop out of the presidential race today. Chris Cillizza speculates that this will help Barack Obama because the anti-Clinton bloc will no longer have a second option.
I don’t profess to have any deep understanding of Democratic politics (or, after this past month, Republican politics either), but one can make the oppositie case. Nearly all Edwards voters are white and I suspect his class-warfare theme may be attracting some lower income and union voters. Whites, low income voters, and union members have been part of Hillary Clinton’s bloc.
If Edwards endorses Obama, that would probably have some impact. Cillizza reports that Edwards will not endorse either Clinton or Obama today and has no plans to weigh in for either candidate in the immediate future. But that certainly doesn’t rule out an endorsement.
