Urquatt was much more thoughtful in his plans. Underwood’s plans are rooted in a naive understanding of American politics by the writers. I am still shocked they made Underwood a democrat.
I read an interview if the show's creators. When asked why the Underwoods are "D's", the said had they been "R's" there would have been criticism "well, there goes liberal Hollywood again." By making them Dems, they appeal to viewers on both sides of the aisle.
This does not stop them from also pitching liberal ideas/values via the Underwoods.
