Regarding the June 15 news article “Climate politics and policies present Obama with quandary”:

Instead of focusing on public opinion polls, the president needs to act on the climate problem by pushing policies, regulations and laws that will reduce the nation’s greenhouse gas emissions as expeditiously as possible. The time for pampering the public has long passed, and it is now necessary to push a bitter pill down the throat of Congress. The president has nothing to lose personally; any action to reduce the U.S. carbon footprint will be on the right side of history. I would rather see the president lose the support of some voters by taking the high moral ground on this issue than to see him wimp out just so that another ineffectual Democrat can win the White House in 2016.
