While it is certainly true that Democrats cut Obama slack on policies where they would slam Bush or McCain, as a fair-minded Republican I note that the reverse holds true as well: Republicans slam Obama and go easy on Bush. I will establish both points in my areas of expertise, the Middle East and Islam.
Obama & Bush - sometimes it matters less what the policy is than who implements it.
Republicans, however, also are inconsistent: they mock Obama's insistence on trying diplomacy vis-à-vis Iran, but Bush did the same, authorizing 28 meetings with representatives of Tehran at the ambassadorial level or higher. Republicans excoriate Obama for setting a deadline for the withdrawal of U.S. troops in Afghanistan but said not a peep when Bush did the same for the much larger undertaking in Iraq in the status of forces agreement to withdraw all U.S. troops by the last day of 2011. Conversely, Republicans give Obama little credit for keeping the Iraqi mission basically in place, only speeding up the timetable.
On a positive note, Republicans did stand with Obama on increasing troops to Afghanistan and they did applaud his taking out Osama bin Laden. In contrast, it is hard to imagine any comparable support by Democrats for a President McCain. Although Republicans have problems with consistency, Democrats are blatantly hypocritical.
