President Obama won reelection with 62% of the votes in the Electoral College. He won 26 states and the District of Columbia, representing 64% of the population. He won the popular vote by more than 4 million votes. He won more popular votes than any Democratic candidate in history (other than Obama in 2008). That's a decisive victory. So if anyone tells you the election was "close," they're ignoring the facts.
The Washington Monthly is an excellent, small magazine. I've been a subscriber for more than 30 years. In 2008, my wife and I had the pleasure of lunch with Charles Peters, the founder of the magazine, who worked for President Kennedy. Paul Glastris, who is now the editor in chief, had an excellent article on what President Obama has accomplished. The Incomplete Greatness of Barack Obama. The subtitled sums it up: "He’s gotten more done in three years than any president in decades. Too bad the American public still thinks he hasn’t accomplished anything." Glastris also had a sidebar listing President Obama’s Top 50 Accomplishments. Both are well worth reading.
Every four years, the electorate gets younger. Most young voters are openminded and see no reason to discriminate against anyone based on race, sex, or gender preference. They replace older voters, who generally are less open to change. Here's an article that shows just how Democratic young voters are:
The article also shows that women, African-American voters, and Hispanic voters are much more Democratic than white men. These groups were the key to President Obama's success in 2008 and will be again this year.
