Here's how one Republican put it during the early part of this decade, before Bubble-Boy had screwed up the Iraq War, the response to Hurricane Katrina, and the American economy: "Elections have consequences." Well, he was right and one of those consequences is that the winners get to set the agenda for their term.
Having lost control of two of the three branches of government, the Republicans are in for a rough ride. Probably the best thing they can hope for is that the economy doesn't improve and Democrats suffer electoral defeats in the 2010 and 2012 elections. If the economy does improve, however, they are in for a long period in the wilderness.
Of course, their own incompetence brought this on their fate. Americans want government to be competent and Republicans have always insisted that they are much more competent than Democrats. Well, that myth, like so many others, was destroyed by Bush and his merry wrecking crew.
Maybe if they had put some distance between themselves and BB during BB's tenure in office, they wouldn't have been routed in two consecutive national elections. But they didn't and they were. As mentioned above, in America, elections do have consequences.
