Obama has been in a position of responsibility for Veteran's affairs since 2005; three years as Senate committee member and 5 years as "president." Blaming Bush is just plain silly. (no article, just this informative headline and a brief comment).

Understand that a politician cannot "accept responsibility" for an issue or problem and blame his predecessor,  at the same time; the two are mutually exclusive  . . . . . . . . .   period.
