Given the substance of both your and Jason's responses, it apparently makes no difference who is President.
Just because no real change has happened for ~12 years doesn't mean it can't happen. Certainly there was a lot of change in W's first term, although it wasn't a change for the better. In terms of how entrenched Wall Street it, it's true that has been ongoing for many years and hasn't changed significantly in that time other than to continue on its trend of becoming more entrenched. A simple look at campaign finance numbers will bear out this claim.
And now you point out that the next likely President, who is of his own party, says that even she thinks he didn't accomplish much
Seems like you made this part up (including the fact that she's the next likely President

).
and that things must change;
Yes, she obviously says that. Have you watched the debates?
if he had done good things, she would promise to continue his policies intact, even though the world is a different place today than when he took office.
She does say this, all the time. On many subjects she says she agrees with what the President has done and will continue in his footsteps. On some others (such as with Wall Street) she says real change is needed. Is this concept obscure?
But it won't matter if she's elected anyway, because she'll be as useless as he has been.
This is an opinion, which you seem to be confusing with facts about Hillary's stated positions. What's complicated about understanding that she says certain things because she must (to try to co-opt some of Bernie's support) but is otherwise a status quo candidate?
I guess we'll have to turn to the GOP candidates for a positive message and hope for real change. They aren't making unrealistic promises and won't take credit for good things that might happen if they are elected, I suppose.
Translation: "If you won't vote for Hillary then you may as well spoil your ballot." At least you're consistent.
It must suck to be President and know that you are so powerless while the GOP complains that everything you do is going to destroy the economy, all of your freedoms and the very future of the nation and thwarts you at every turn. So, he can't do anything positive, and it wouldn't matter if he did, because everything he has done is wrong and have made things worse.
The first part of this statement is true; it definitely must suck. The rest of it makes it appear that you're making straw men out of fairly clear statements.
In a farcical reality, why even vote?
A sentiment echoed by many people over the years as voter turnout has declined. It's hard to muster the energy to vote when you don't feel it will accomplish anything. Since recent studies have shown that the will of the people is barely relevant in terms of policy compared to special interests one can hardly doubt that this will have a demoralizing effect on the populace. There was a brief spike in both the 2004 turnout (possibly a war-time anomaly) and in 2008 (likely due to people hopefully rallying to Obama's cause), but overall it seems to be clear that many people believe
it is a farcical reality. Naturally your solution is "if it ain't broke don't fix it", even though the sentiment of much of America seems to be that it actually is quite broke. My solution would be to try to fix it. Crazy, right?
