What is the appeal of third parties like New Milford First? When disenfranchised voters see no difference between the two major parties, a vote for a third party candidate is essentially a vote of "no confidence" in the two party system.
When the block of disenfranchised (third party) voters is large enough, their "protest votes" can and do effect the outcome of elections. Some 20th century examples are the "Bull Moose Party" in 1912, the "Dixiecrats" in 1948, Ross Perot in 1992 and Ralph Nader in 2000.
In each of these examples, third party "spoilers" cost the incumbent president's party the White House. This is possible on the state or local level as well, depending on the extent of voter dissatisfaction with the status quo. In other words, New Milford First voters may not be casting their ballot for Bob Kostes et al. They may simply be voting against all the other choices...
