A democratic president and the magic number of 60 makes for no balance of power...

Let's be blunt, one of the main reasons why a political party would want to have the president be of their party and have the "magic number" of 60 senators is so that there is no balance of power. They would be able to get through whatever they wanted to pass with little ability to have any dissension. It's every political parties dream...and the Democratic Party has a chance of seeing that come true.

Of course it's not how our government was created, it's not how our founding fathers planned and we were even warned:

The alternate domination of one faction over another, sharpened by the spirit of revenge, natural to party dissension, which in different ages and countries has perpetrated the most horrid enormities, is itself a frightful despotism. But this leads at length to a more formal and permanent despotism. The disorders and miseries which result gradually incline the minds of men to seek security and repose in the absolute power of an individual; and sooner or later the chief of some prevailing faction, more able or more fortunate than his competitors, turns this disposition to the purposes of his own elevation, on the ruins of public liberty.

Without looking forward to an extremity of this kind (which nevertheless ought not to be entirely out of sight), the common and continual mischiefs of the spirit of party are sufficient to make it the interest and duty of a wise people to discourage and restrain it.

It serves always to distract the public councils and enfeeble the public administration. It agitates the community with ill-founded jealousies and false alarms, kindles the animosity of one part against another, foments occasionally riot and insurrection. It opens the door to foreign influence and corruption, which finds a facilitated access to the government itself through the channels of party passions. Thus the policy and the will of one country are subjected to the policy and will of another.

However, we've already established we don't learn from our history, and if the magic number is reached and Obama is elected? The Democrats can no longer blame Republicans, they would have to take full responsibility for the course of our country. That, would be a good thing as at least someone would have to take full responsibility rather than the endless game of finger pointing.
