Does it really matter?

Does it really matter if we vote? Does it really matter who is President?  To the first question, I say yes.  It matters if we vote and it matters whom we vote for. Right down the line from President to Dog Catcher.  Someone told me they didn't care about who became Governor.  We should care. There is a lot of control at the state level.  
The answer to the second question is a little more complicated.  Grover Nordquist, I believe, said we just need someone with enough digits to hold the pen to sign the bills.  If you look at how many or what kind of bills have gotten through Congress in the last 3 1/2 years, it really doesn't matter who the President is.  President Obama gave us lots of hope for some change, but he has really gotten very little of it done.  What he has been able to get done has be very good and sometimes even great, but his hands are basically tied by Congress. 
Mitt Romney on the other hand, now he's saying he has all these ideas for helping the middle class, but he won't tell us what they are.  Just like he won't show us his taxes.  And now this video has come out that proves the disdain I knew he had for most of this country.  Why would anyone vote for him?  Honestly, I want to hear a real solid reason why someone would vote for this man.  And it has to be other than, He's not Obama.  
A friend of mine posted this question on facebook. She's still waiting for an answer.
