Perfectly stated.
With all due respect (and I mean that after reading your profile), the 'fretting' is because that the democrats are STILL fighting the elections of 1994, 2000, 2002 and 2004. They refuse to acknowledge that THEY lost. That the American people have rejected them and their "ideas" over and over, and over again. They're re-fighting all their losses. To them it's always 'election season'.
Ergo, it's not 'about' Bolton, like it wasn't about Condi and every other one of Dubya's nominees that have been trashed by these gutter snipes (which includes that phony baloney 9-11 commission), it's about Bush - period. The RATS are determined to thwart everything he wants done or tries to do. They're determined to deny him his well deserved legacy and turn him into a Clinton, i.e.; a failed president. Heck, this president has freed more people from tyranny than any other in history, especially their hero FDR who contrarily subjugated millions INTO tyranny, and it makes them apoplectic.
In many respects it's almost a replay of what then majority leader George J. Mitchell (D-ME) did to Bush 41 and "read my lips". Mitchell back stabbed him, basically pushed through the tax hike, but "41" got the blame. Dubya "ain't" gonna fall for the RATS tricks like dad.
