Maybe we citizens should band together and do everything we can to get rid of these two parties. The egos in Washington have gotten out of hand. But of course us Americans can't get along because there's far too many dumb people. Didn't somebody in here mention something about "dealing with it"?
Two problems:
1) We've been saying it for
years
2) Strong political adversaries, historically, are absorbed into the two-party system in order to maintain power. Take for example the growth of the Populist and Greenback Parties, some of the first political parties to gain a pretty large base in the Mid-West during the 1890s and early 1900s. There was enough of a groundswell on one or two points of interest that the Democrats essentially said "screw it," took their platforms, and consequently those votes with it. Republicans have done much the same, taking in the Dixiecrats following the Civil Rights movement, and certainly there has always been the love/hate relationship with the Libertarians.
What it comes down to is that after 208 years of the current two-party system with its various names and disguises, unless we change the way in which we vote or the system altogether, we are stuck with the slightly left of center, and the slightly right of center, both of which have to do their best to not only appeal to their "base" voters, but also the growing number of independents in the center.
The good news is that partisanship, for the most part, has decreased steadily with newer generations of voters in the past 50 years. Newer voters are far less-likely to meet or match their party's platform line-for-line, and it is a partial explanation as to why McCain keeps calling himself a "maverick," as the Independent streaks of most Americans increase. This means that, more or less, people are going to be issue-driven with their votes, meaning (God forbid!) that candidates often have to address the issues more often. Well, in theory anyway... So, in the end, while we are otherwise "stuck" with the Democrats and the Republicans, it seems reasonable that we will either see the emergence of the Independent party as a considerable power, or we will continue to see the coalition expansion with the DNC and GOP as usual.
