Voters in Virginia, Maryland and Washington, D.C., have their say tomorrow, but the John Edwards primary is already in full swing.

Sen. Hillary Clinton made a clandestine visit to her former rival Thursday at his home in North Carolina to seek his support.

Sen. Barack Obama recently had to reschedule a meeting with Edwards, but soon enough, it will be his turn to make a pilgrimage.

Both Clinton, clinging to a narrow lead in delegates, and Obama, riding a wave of wins in the past week, covet the endorsement.

Which way is the former North Carolina senator leaning? Like Bill Richardson, he seems to be genuinely and outwardly conflicted.

Hmm… to endorse Option A, Option B, or neither …

Citing sources close to Edwards, The New Republic claims he likes Obama personally, thinks he intends to change the status quo, but isn’t sure he’s ready - and worries he’s not tough enough to take on the GOP.

On the flip side, John Edwards is lukewarm on Hillary Clinton and doesn’t think she’d change anything, but thinks she’d pummel the GOP.

Whether Edwards will soon endorse in the Democratic race is unclear - CNN reports that some advisers are encouraging him not to endorse either - it would be a nice boost for either candidate, to be sure.

Edwards and Richardson (who we would expect to gravitate towards Clinton, but has not, at least yet) are the top endorsement prizes out there.

While Al Gore would top both in terms of impact, there has been no sign that the environmental Goracle is ready to plunge back into politics.

An apparent alliance between Barack Obama and John Edwards was clearest in the days just before the New Hampshire primary, when Edwards embraced Obama and chastised Hillary Clinton as an agent of the status quo.

One would think that someone who rails against special interests and the current state of Washington as John Edwards does would make an easy call with support of Barack Obama - the anti-establishment candidate with no baggage.

But, as with Richardson, all bets are still off.
