Past history has shown your wrong. The key element to Obama's policies, which is absent McCains is Paygo. Republicans eliminating Paygo in favor of partisan tax cuts was one of the most irresponsibles acts in my life time.
With Paygo they have to find the funding for any program. They cannot borrow the money as irresponsible "borrow and spend" republicans have done.
Either they find the money by defunding existing programs or they wear the odium of raising taxes and have to meet their constituents to explain such tax hikes.
That was the one thing in the debates many independants were wanting to hear that Obama committed to. Reinstituting Paygo, where as Republicans would rather watch our republic die than balance the budget and there by, god forbid, risk a tax hike.
When did REPUBLICANS eliminate PayGo? Are you truly so fucking partisanly ignorant to deny we have been using deficit spending since before WWII? Past history has been deficit spending under both democratic and republican president and congresses. True paygo has not existed since before WWI. The Great Depression was, in part, an economic adjustment to the (necessary) deficit spending that occurred in fighting WWI.
Raising taxes where Obama keeps promising not to raise taxes on incomes lower than 250K is EXACTLY the area I believe him to be flat assed lying. Unless he is existing in a drug induced fantasy, he knows that he will have to raise taxes on everyone above subsistence income to fund all his ideas - or even half of them - and even then it will not be enough because the slumping economy will result in declining revenues no matter how high he shoves the tax rates.
Additionally, PayGo or not, Obama's proposed policies of raising taxes on investment income, dividend income, corporate taxes, etc. coupled with proposed protectionist style modifications to trade treaties is EXACTLY what Carter tried to instill under very similar economic circumstances (rising unemployment, oil prices, supplies of crude limited, bank troubles, etc. - though the situation when Carter was sworn in was not nearly as bad.) The only thing he has NOT proposed is induce price freezes, and when his policies shove inflation even higher than it is already headed, I would not be surprised to see him try that, too.
Why is it Obama (and seemingly, you) expect different results from the same types of actions under similar bad economic conditions? With the starting situation being significantly worse, the economic reaction to poor economic policies will be correspondingly worse.
McCain's ideas, if implemented, won't do a damned bit of good. But neither will they make things any worse than they will get if nothing is done.
