Bloomberg TV joins the debate fray tonight, hosting its first-ever presidential debate. Charlie Rose will moderate the GOP debate at Dartmouth which will be at a Rose-esque roundtable (actually more oval); no podiums. Bloomberg TV’s Julianna Goldman and The Washington Post’s Karen Tumulty will join Rose and the candidates at the table.

The two-hour debate starts at 8pmET. Because Bloomberg is not a Nielsen client, the network tells us there won’t be television ratings for tonight’s event.

The GOP candidates are back at it next week when CNN’s Anderson Cooper moderates the CNN Western Republican presidential debate in Las Vegas next Tuesday at 8pmET.

> Update: An emailer asks: “Where is Bloomberg TV shown?” Here’s the answer.

BloombergTV's Margaret Brennan and Al Hunt at Dartmouth University ahead of tonight's GOP debate.
