It has been a constant theme in the mainstream (i.e. Liberal) media since at least the 1980's: Republicans pander, while Democrats "move to the center". Liberals cannot accept that anyone (certainly not Republican office seekers) could be sincere about the "right wing" positions they hold, be it pro-life; nationalist-patriotic; pro-religion; against gay marriage; whatever. When Republicans speak on these issues, they are"pandering" to their base constituencies.
Democrats, of course, never pander; they are sincere, courageous, advocates of their positions, even when they speak out in favor of (no matter how gingerly) positions that are generally considered to be conservative. At best (sometimes said with a note of disdain or exasperation) they are "moving to the center", which is considered no sin if it mollifies the great unwashed and gets the Democrat elected so he can do "progressive" things. Nothing about cynicism or (heaven forbid) pandering.
When Republicans advocate any "unacceptable" (i.e. non-Liberal) position, they are "exploiting wedge issues", another great sin, since some ideas are simply unacceptable in polite, Liberal, circles. Liberals cannot conceive the idea that anyone could possibly hold such positions and still be sincere. Furthermore, "wedge issues" are things that are considered beyond discussion, whether they are right or wrong. At a minimum, they are considered "divisive" - never mind that that is exactly what elections are supposed to be about, issues that "divide" the electorate. By definition, any issue is considered divisive if it falls outside the Liberal consensus.
These attitudes in the media are so constant, that they are never questioned or open to discussion. All this is doubled in spades (no pun intended) when it comes to the Anointed One. A current example: When Bush spoke of faith-based initiatives, he was pandering to the Religious Right; when Obama advocates continuing and expanding such initiatives he, of course, is only drawing on his background as an "advocate" with a long history of association with the "Black" church (Rev. Wright, where are you?) and its community work.
