Is Obama acting within the constitution?

The U.S. Constitution and Barrack Hussein Obama - are they in synch?

There is much going around the internet, and by email, regarding Obama's eligibility to be President based on any number of issues which most of you have already heard about so I won't mention them here because it's not pertinent to this blog. Many Americans are almost up in arms over the spending and government takeover of the automotive industry, the banks, the insurance industry, and of course healthcare. Presidential and Congressional spending is stratospheric! Mr. Obama is leading the way into accelerated change. This is precisely the CHANGE he talked about in his Campaign. The problem is, he was somewhat deceitful with you and I. Does America need this much CHANGE? Why would a 48 year old man think that he knows best for 300,000,000 other Americans? He's ignoring at least half of us. He's acting on behalf of one party only at the expense of the other. Is he really off track with an unrecognizable leftist agenda or are many of us simply afraid of change?

My main question to you is this; do you believe by his actions, his deeds, or in his words that Obama is acting within the guidelines of the United States Constitution?
