Why I Won't for Obama in 2012

I voted for Obama in 2008.  I admit it - I bought into the hype, and the whole hope-and-change bit. 
Well, 4 years later and I can tell you that "hope-and-change" was little more than "smoke-and-mirrors".  Granted, Obama is intelligent, interesting and a fabulous orator, but as a leader he is woefully inept. 

In my opinion, the president has two MAIN duties above all others: 1) protecting our interests at home and abroad; and 2) ensuring (as much as possible) that the economy stays healthy and that people can find jobs. 
So, how has he done? National Security: bin Laden is dead. This was big. However, since then, his record has been lousy. He routinely ignores his security/intelligence briefings, and his response to the Middle East crisis has been (at very best) extremely lukewarm. Iran will very quickly become a nuclear power, and he's done almost nothing to stop this. (Case in point: he's too busy to meet with Israeli PM Netanyahu, but yet has time to film "Letterman". REALLY??) 
The Economy: again, abysmal record. Unemployment is still ridiculously high; real family income is practically in free fall; and he really truly feels that government is "the answer", as opposed to the private sector. 
Now, I'm FAR from a Romney fan, but I find myself asking: do I want a charming intelligent yet INEPT leader marching us 4 more years towards Socialism.... or do I want a somewhat stiff and cloddish capitalist who UNDERSTANDS Economics 101 and wants to work to pull us out of the quicksand, before we sink deeper? 
In my mind, the answer is very clear.
