Economic fault lines to watch for in Thursday's debate

Expect a lot of economic red meat and Obama-bashing from Republican candidates when they step onto the debate stage for the first time Thursday evening.

With 10 candidates in the main event and a half-dozen in an earlier panel, the candidates will be under pressure to distinguish themselves from the pack. All the Republicans will tout low taxes and spending while blaming President Obama for slow growth, but they’ll have to find ways to create a unique appeal to conservative primary voters.
