Sad to See Congress Polarized Against Country's Greater Interests

I have been watching the United States Senate floor proceedings off and on for the last few weeks on C-Span2, which on my Gainesville cable TV lineup is on channel 81.  As you may already know, after last November's elections, the Republican Party regained majority operational control of this body and now holds a 54-46 advantage over the Democrats.  This puts them in line with the House of Representatives, which has been with a GOP majority since 2011 and places Congress as a whole in opposition to President Obama.  They can pass bill after bill that they want, but if it's something that the President opposes, he'll most likely veto it...and it's highly improbable that either the House or Senate will be able to muster the two thirds super-majority to override...so what we have here is a stalemate if either side decides to take a strictly ideological stance.  Unfortunately, that seems to be what the Rebublicans have done, first by inserting (and later withdrawing under pressure) provisions overturning Obama's recent executive action concerning illegal immigration within a crucial Homeland Security funding bill...and most recently putting anti-abortion language into a human trafficking bill, language that the Democrats would very predictably oppose.   Now Senate Majority Leader Mitch McConnell has said that he will retaliate for the Democrats holding up that bill by refusing to bring to the floor the nomination of Loretta Lynch as Obama's choice for Attorney General to replace outgoing  Eric Holder...despite the fact that Lynch seems to have the votes for confirmation and is more highly regarded by the political right than is Holder.  The atmosphere in both bodies is becoming more heated and contentious, with each side drawing their own lines in the sand and refusing to step across.  It's more than a little disheartening to me when I see grown adults, who supposedly represent the highest elements of our society as they have been democratically elected to represent us in a constructive and mature manner, behave this childishly when they are in a position of such responsibility and authority to work together for the greater good...
