First, let's go into a bit of history. There have always been many wings of each of the political party in the United States. In the Republican Party, these can be most easily simplified into the 'Conservative' and the 'Moderate' wings of the party. The modern status of these has been seen since at least the 1960's, when Barry Goldwater represented the 'conservative' movement and Nelson Rockefeller the 'moderate' movement. Both wings of the party were instrumental in winning across various states, and it is the combination of the two wings of the Republican Party that gave the GOP its historic 1984 landslide.
However, the two wings have been at somewhat at odds in recent years. 2000 brought about the election of the conservative George Bush, and his later years saw historic losses for the GOP, most clearly highlighted by the catastrophic losses in 2006 and 2008. The 2012 nominating process saw a new and somewhat disturbing trend in GOP. The massive infusion of Super PAC cash in the primary season meant that moderates and conservatives alike wound up with a candidate whom neither wing particularly approved of-and yet hundreds of millions of dollars which would have been much better spent on showing the positives of the GOP candidate were wasted bashing other candidates-moderates and conservatives alike.
Now, we're unfortunately starting to see the same mentality crop up in preparation for 2016. Potential candidates are still largely silent on what they'll do come campaign season, but the crop of candidates is growing quickly. Just as quickly, supporters are starting to bash other candidates as either 'too moderate' or 'too conservative'. However, why can't we find areas where we agree, and not just areas where we disagree? I'd love to see a primary season in which Reagan's 11th Commandment is followed. Please, let's not bash another candidate just because we happen to support someone else.
