How many bills have NOT been put to vote in the Senate this year? And why?

It depends on how you define a bill. If you leave the batsh*t crazy tea partier stuff out, the Senate has considered every bill and passed several of them. If you include the what is it now? 46 or so bills to kill Obamacare along with all the other time-wasting nutty stuff, it looks like the Senate is picking on the House but it only "looks" that way. Part of the Senate's job is to consider legislation that provides for the common defense and general welfare and to ignore the reckless stuff. (Article I Section 8)

EDIT

Here's the problem. I'm sure many of these tea partier guys in Congress are okay people and they just have extreme views. If they didn't, the Koch's wouldn't have financed their campaigns. These guys are dentists and grocers, one is a beauty pageant mom... That may have been fine when we were a small inconsequential country but today we have 300 million citizens, we provide the world's reserve currency and we have the largest economy the world has ever seen. We actually need legislators that have some education in government, economics or law and ones that have some experience. There's a legitimate reason why the legislation leaving the House looks stupid these days. Amateurs are writing it.

i put many bills in the hopper but they don't usually get out of committee.

354 to date. Harry Reid has the honor of being the Senates Greatest Obstructionist.

the blame game

Anything that came from the House on a straight party line vote, which describes almost all of the bills they passed. They are worthless total bs bills which they lovingly call "jobs bills."

Any and all bills, regardless of content, that end with " and the repeal of the ACA" have been tabled; so I suppose most of them.

I lost count but over 30 jobs bils the last 2 years alone. Blocked by Harry Reid/Obama so as to make it look like the Republicans are doing nothing. When exactly the opposite is true.

anything that originates from this house ain't worth the time it would take to vote it down

Zero.
