More of a Bush car really. Federal tax credit was signed by Pres. Bush for plug-ins (he also had support of tax credits for hybrids such as the 100% imported Prius). Chevy was designing and defining the Volt specs during the Bush presidency. Obama was "just hanging around as President' when Chevy put the car out.
Republicans should be all over EVs to support their agenda of "North American Energy Independence by 2020". Of course, that just means more oil production in N.A. during this timeframe. They don't realize that the Nat. Gas production can feed electric companies and that can feed EVs so less oil is even needed for import. They support the oil industry by supporting production but miss a great opportunity to actually use it's products wisely in a fiscally and ecologically conservative way. Electric vehicles would cut ongoing costs for government fleet vehicles, improve the import/export factors we have, improve GDP by more local manufacturing (Leaf, Volt, Tesla, Ford Energi) and perhaps bring drivers back to more domestic brands instead of their continued latching onto imported vehicles from Germany, Japan, Korea and other locations.
