It takes 218 votes in the House to pass a bill, There are 257 Democrats currently in the House. Leaving 178 Republicans. Even if EVERY Republican votes against a bill it still requires that 40 Democrats ALSO vote against the bil in order for it to fail. Republicans have NO power in the House at all.
It takes 51 votes in the Senate to pass a Bill. Even if every Republican voted against the bill it would require that 9 democrats vote against the bill. The only power Republicans have is filibuster and until a week ago they did not even have that as the Democrats had 60 votes. And there are several Liberal Republicans in the Senate. Filibuster will not work on everything.
On the surface, it would appear that you are correct. And the simple minds will cheer you on. But the numbers are not everything, they are not even what you have described them to be. In the House, you are correct, and the House Dems have pass pretty much whatever they have wanted to pass.
The Senate is a different animal. Let's look at your claim to the Dems having 60 votes. There are 58 Dems, 40 Reps, and two independents (one of which is Lieberman who since 9-11 has turned pretty much into a republican or at the least a not reliable Dem vote). Also, when is the last time you saw Dems do ANYTHING in lockstep (and I'm not sure I'd want them to if my experience with the GOP is the example).
Secondly, in the Senate, unlike in the House, there is a little thing called a filibuster. You can't get to the point where 51 votes can pass a bill if you can't get past the filibuster and the number of filibusters has increased dramatically since the GOP lost congress. Senate operations have always been difficult for simple minds to understand. They are burdened with the outdated concept that the senate operates on a majority rule premise. It doesn't. It operates on a 60% rules premise. It takes 60 votes of the senate to vote to proceed to the step where 51 votes can pass a bill. BTW, rember when Chaneney threatened the 'nuclear option' when the GOP had control of the senate? And the Dems were screaming foul? Well that's because the Dems were filibustering something or the other and the GOP couldn't get to the point where 51 votes could passed the bill.
So, for you, and a whole lot of Dems, their supposed control in the senate was and is an illusion.
