"Bush is trying to cut Medicare, Bush's budget had a lot of cuts it was the dems and rino's that stopped those cuts."
How did he try? Did he try to not sign the bill, yet somehow his pen went right ahead and did it anyway? The President has a very clearly mandated constitutional role when it comes to bills coming to him from Congress. Firstly, he decides if he approves or disapproves of the bill. If he approves, he signs it.
Your argument seems to be that Bush doesn't approve of the bills, yet is signing them anyway? That is what you're saying, right? To what would you ascribe this abrogation of his mandated role?
Most bills the president has no power over whether they pass or not. For example the recent transportation bill passed with a veto proof margin making Bush's signature meaningless.
