$10 says Obama appoints no Republicans to his cabinet. This isn't about hope, he just wants to let the Democrats run the show. He won't reach across the isle; he'll stand in the way of that happening.
Good. Republicans lost. Why should they be rewarded?
Uh ... you do realize that your guy campaigned on 'working across the aisle' and tossing aside partisanship, right? Or was he being a liar?
But seriously, if he appoints any Republicans, it'll be very moderate Republicans (Obamacans) in the form of Lincoln Chafee, et cetera. He will never reach across the aisle to conservatives because Obama's 'bipartisanship' doesn't extend that far.
And because the far-right conservatives that make up the Republican party are way out of the mainstream. The American people did not vote for divided government; they very solidly voted for a Democratic President, a Democratic Congress, and a Democratic Senate.
