Why do people fall for claims that our budget problem's are the President's fault?

Check this claim and this one and this for a small sampling of the litany of lies.

The problem with these claims is that there’s this amazing document called the US Constitution. Most Americans have heard of it, but apparently few even among our congressmen and op-ed writers know what it actually says, and that leaves them vulnerable to political hucksters and their litany of lies. Don’t you think that all American voters really should read the Constitution? Doing so just might calm the common paranoid fears about an Obama takeover and presidential spending run amok.

OK, most Americans do know about the Second Amendment, or at least one selected part of it, and little bits and scraps from the First Amendment. But they really ought to study the whole Constitution. You see, it assigns the power of the purse ONLY to Congress. And Congress has been spending a whole lot more than it takes in with taxes for quite some time now. In fact, it began doing that under our wonderful Ronald Reagan. At Reagan’s request, Congress slashed the top tax rate by 60% and drastically increased government spending. We’re now taxing at the lowest rate as a percent of GDP since 1958. Now some may not have thought about it, but the nation has grown in population and technology in the past 55 years. Logically, it’s government today is going to be more costly than government was shortly after the end of WWII.

As terrifying as that wicked, evil Obama may be, he can’t spend money. He can’t set tax rates. Per this Constitution that I mentioned, that power rests with Congress and the spending part rests specifically with the House, where all budget bills must originate. Sadly, we have a Speaker for the majority party in the House who apparently hasn’t read the Constitution either. He’s somehow gotten himself convinced that his failure to develop a fiscally sound budget is all somebody else’s fault. Maybe Obama should do it, or Harry Reid. Maybe Vladimir Putin should take a stab at it, or we could retain a fortune teller to figure it out. But certainly not John Boehner and congressional Republicans. Because them doing it would be doing their job, and that might take time away from endless fundraising and loitering with lobbyists to rake in their lucrative rewards.

Just about everybody agrees that government is currently broken. The 112th Congress did the least of any Congress in modern history and garnered an approval rating of 12%. The Flu virus has a higher approval than that! How do we fix broken government without the voters knowing what good government is supposed to look like, what the US Constitution requires of it?
