It is Bush's fault

Majority Leader Harry Reid (D-Nev.) said Bush “is impossible — and has been for seven years — to deal with.”
Reid sought to portray senior White House adviser Ed Gillespie as an incarnation of Karl Rove and a mastermind of intransigence.

What has the Senate Majority Leader so frustrated? Well, the main problem seems to be that Bush is responsible for the House and Senate dems not being able to agree on a way to pass legislation that funds the government. The House wants to raise taxes and the Senate won't let them. Some dems want to just reduce spending by cutting off earmarks and none of the phony politicians (from either party) want to do that. Too draconian. The far left wants to insist on PAYGO which was passed when the dems took over Congress to be sure that the Bush tax cuts could never be allowed to stand beyond their designated life. More moderate dems are not so rigid. Blue dog dems elected in 2004 are feeling the heat of coming re-election and want to be viewed as financially responsible, so they have to cling to PAYGO since this sounds like it is sensible.

Bottom line the inability of the dems to come to some sort of agreement is Bush's fault except this article seems to highlight internal conflict more openly.
