Democrats' hopes for a friction-free national convention seem to fall by the minute.

We told you in today's print and premium editions that other than some typical Democratic fussing and arguing, most of Georgia's delegates to the Philadelphia convention that begins Monday expected a smooth experience.

Or at least smoother than what we witnessed in Cleveland last week at the Republican National Convention.

But that was before a number of Bernie Sanders' supporters began to complain -- some loudly -- about presumptive nominee Hillary Clinton's decision to choose Virginia U.S. Sen. Tim Kaine as her vice presidential nominee.

Things became worse as hacked emails revealed that a Democratic National Committee official questioned Sanders' heritage and that the national party was not keen on Sanders' continued campaign.

We'll have more on this as the day develops (i.e., once we land in Philly this afternoon).
