Yeah, he wasted his time on insignificant crap like disentangling America from not one but two disastrous wars, addressing a financial meltdown, affordable healthcare and bringing employment and financial markets back to pre-recession levels.
And how is all that 'insignificant crap' working out for America ? 'Disentangling' from Iraq has now led to radical Islamists being in charge of much of the country and Syria (another story altogether, let's talk about 'drawing a line in the sand'), how is the recovery exactly coming along for the average American and how is that 'affordable' healthcare working out? Think it will be a while before we know the answer to that. Obama is also the single most partisan president in recent memory, in fact, Americans think he is the worst president since WW2, even worse than Bush. He passed health insurance reform without a single Republican vote. The Republicans asked for tort reform to be attached to the reform, Obama said no to keep his lawyer buddies happy.
Bush may have initiated many of those issues (who 'inititated' the financial issue can be debated forever), no debate that Bush's decision to go into Iraq was an absolute disaster, but, Obama knew what he was getting into. 6 years later it's pretty tough to continually blame your predecessor. If Obama's not to blame for the current happenings, then you are saying that he is grossly ineffective as a president in taking charge.
Call me 'conservative' if you like, my political beliefs are much more broad than that. I do believe though that Obama was elected as the anti-Bush, not for his actual leadership skills, he will be one of the worst most devisive presidents in recent history. Hell, he used the IRS to investigate conservative groups, used an arm of the US government to oppress his opponents. That is repression of a specific group by the government.
