President Obama travels to Detroit today to talk about the need for increased taxes on top earners to finance federal spending, and is using an announcement of a $100 million investment from German auto giant Daimler to illustrate that his economic prescription is working.

Obama is not likely to discuss another big business story of the day – the sale of the assets of battery maker A123 to a Chinese competitor. A123 spent at least $132 million of its $249 million stimulus package grant to build two Detroit-area factories, including one in Livonia, right next door to Redford Township, where Obama is speaking today.
