The primary GOAL and perhaps the only goal of both the Republicans and the Democrats is to increase their power. That means getting more members into positions of power and responsibility. It might be by getting members elected to office or it might be by getting members appointed or even hired into key positions of power.
The GOAL of parties IS NOT to improve your life, improve the economy, increase our security or help you out. Those are occasionally means to an end! And the END GAME is to increase their power and control.
If the Republicans REALLY WANTED to accomplish any of their stated objectives they would stop their relentless pattern of obstructionism and seek common ground with the Democrats. Likewise, if President Obama REALLY wanted to reach his goals he would cease his relentless campaigning and compromise with Republicans.
Why doesn't this happen? Because the GOAL is to get more members elected. President Obama is considerably more interested in getting reelected than in helping Americans. So he very falsely claims Republicans stand in the way of issue "A" or proposition "B" because he wants the issues to aid his reelection.
Occasionally politicians actually speak the truth. Republican Senator Mitch McConnell made that mistake when he honestly said his main goal was to "defeat President Obama," His Number One Priority wasn't reviving the economy or putting people back to work, it was to defeat the President four years in the future!!
My advice to my fellow Liberals (and to Conservatives, too), is to relentlessly work to achieve your goals. Look for pathways to success. That will OFTEN lead you to support, work with and even elect a member of the opposite party. More often it will lead you to look for solutions outside of government.
Think outside the box. Be driven by your principles and not guided by the false promises of one candidate or another.
