Ok, leaving aside that there really is a pretty apparent disparity between the parties. 
What we have here is a check on the balance of power to the executive branch. Namely the ability to nominate only judges that agree with your political ideology. For what it's worth, that's an important check. Judges by the nature of their role in government should be as neutral as feasibly possible. We shouldn't need to counterbalance conservative judges with liberal judges is what I'm saying. With that in mind, the previous administration went out of it's way to appoint ideologically biased judges. The very extreme were blocked by the then minority Democratic party. In other words not great but still a reasonable facsimile of function.
The current situation is EVERY SINGLE nominee is being blocked. No reason is given, other than it's someone President Obama wants. Most recently I read that Paul wanted to block Yellen pending an Audit of the fed. Those are two independent things, why hold one up in order to achieve the other if the other has merit?
Five years of obstruction, in other words. This situation is unprecedented in history. Blame the Democratic party for what they did during the Bush administration but people still got appointed. Most of them actually.
Still, if you look at the chart you can see that they used cloture and filibuster as well, as has every congress going back to essentially 1960 in rising numbers.
People, politicians have taken this important tool and turned it into a petty tool to obstruct their way into getting what they want rather than advancing their own agenda to the American people.This tool has been losing it's value every time it's used for this purpose petty. It's time to replace it with something that works, and can't be abused as it has been for the last five years.
This has been a long time coming, and in all honesty was only a matter of time anyway. Given that the current Republicans are vowing to 'make them regret' doing this, it only highlights the need to fix this tool.
You know what it reminds me of? It's a bit of a tangent but bear with me. It reminds me of a Republican senator talking about getting enough votes to impeach the President. Left out of his statement was a reason for impeachment. Who cares, just make something up later, and if it doesn't work do it again, and again , and again until it works. Kind of like voting to end Obamacare 41 times. Why do it 41 times? Who cares, all that is important is to show that they don't like Obamacare.
You might like to talk about how both parties are the same, but I don't see it.
I don't see anything constructive coming out of the Republican party; only obstructive. If you think it's balanced then I suspect you're getting your news 'unskewed', to reach back to the recent election for a term.
