Who will Warner endorse?

While Bill Bolling seeks supporters for an independent run, a question he must consider
Who will Mark Warner endorse in the fall?
As the face of Virginia moderation, will Warner lean toward a moderate Bolling?
Or just back his fellow Democrat - Terry McAuliffe.
In theory, people like the idea of an independent candidacy.
Come the stretch run of the campaign, it will be about the partisan team.
If Bill Bolling's big announcement comes with a major Democrat at his side, he could have a chance.
Without that, it's a split of the Republican vote.
Not much good moderation will come with Democrats in the leadership.
