Millions of Americans are unhappy with their choices for president in this year’s election. According to Real Clear Politics’ average of all the latest polls, Donald Trump has an unfavorable rating of just over 60%, with 33.8% favorable. Hillary Clinton doesn’t fair that much better with an unfavorable rating of 53.1% and 43% favorable.

While those numbers will likely change before November, the fact that the country’s election process could result in such unpopular candidates receiving the nominations of our two major parties is a sad statement on the health of our democracy. Meanwhile, the candidate with the highest favorable ratings, Bernie Sanders (50% positive and only 36.8% unfavorable), has been eliminated from the race. One could reasonably expect that in a democracy with an open and fair electoral process the candidate with the highest favorable rating would still be running with a good chance of winning. Then again, many have questioned the fairness of the Democratic primary process which awarded the nomination to Sec. Clinton.

Nevertheless, despite being the most popular candidate, Sanders has endorsed Clinton rather than run on a third party ticket. His primary reason is his belief that we must do everything we can to defeat the very dangerous Trump candidacy. A third-party run by Sanders could result in a Trump presidency. Understandably, Sanders is not willing to take that chance.

But what if there were an already viable third party with an established structure in every state? Would a Sanders run make more sense then? Aren’t there more than two major political viewpoints in this country that deserve the voters’ consideration on election day?

After all, who do Trump and Clinton really represent? Trump’s supporters are the base of the Republican Party, mostly male, white working class, social conservatives. Some of the Establishment Republican businesspeople, on the other hand, have deserted Trump for Clinton or Libertarian Gary Johnson.

Clinton’s support comes mainly from the Establishment wing of the Democratic Party along with minority voters and some aforementioned professional Republicans who cannot stomach Trump. Meanwhile, progressives and many younger voters believe they have been robbed of any real choice since their candidate, Sanders, has left the race.

At the same time, many Independents, a great number of whom supported Sanders in the primaries, also feel they have no viable choice. When Independents could vote in this year’s Democratic primaries and caucuses, Sanders beat Clinton, often by large margins. Therefore, it is a reasonable possibility that Sanders could beat Clinton and Trump in a three-way race. The combination of progressives, the youth, new voters, a sizable portion of the Democratic base and many Independents could put Sanders over the top, assuming the elections were run fairly.

As Clinton solicits Big Money donations and disaffected Republicans’ votes, it seems highly unlikely that her policies, assuming she wins the presidency, will meet the progressive standards set forth by the Sanders campaign. Consequently, Sanders is preparing to launch Our Revolution to advance his proposals for a better future for all Americans. To create that future, a broad-based movement to establish a viable third party must begin now.
