This is a post from the Times UK about a stratgy Obama may try. Namely, he is thinking of offering republicans spots in a prospective Obama administration in order to get republican votes.
Ok so what right?
Well, a few of the people hes thinking of using are currently US senators.
Now, it may be just me, but it seems to me that US senator is probably the most prestigious elected office in the federal government next to US president-the latter being the most powerful job in the world. Thus, it seems to me that he is assuming a person would be willing to leave the Senate, in order to join the Cabinet of a president.
Last time I checked, elected officials were supposed to be more influential and powerful than appointed ones. Yet, this seems to indicate people would rather hold some relatively benign cabinet post (say-secretary of the interior) then be a elected official of the highest caliber in the federal government.
