The total disaster that is Donald Trump has put a number of states traditionally thought to be 100% republican in play. Arizona is one of them, as are Texas and Utah. Trump's candidacy has altered the way we view elections, and it is also altering how we view which states can be won.
Arizona is a swing state, and that is always important in an election year, whether the election is close or not. There is a lot riding on this election and what happens in Arizonia could make it or break it. We still have a few more weeks before we find out the results.
No, Arizona will not be a significant state in this year's presidential election because Clinton will win so many other swing states that Arizona will only cushion her victory. It is important that Arizona may go blue, but it will not be the deciding factor in this year's presidential election.
Every vote, everywhere, for every candidate, would be politically relevant and equal in every presidential election.
No more distorting and divisive red and blue state maps of predictable outcomes.
No more handful of 'battleground' states (where the two major political parties happen to have similar levels of support among voters) where voters and policies are more important than those of the voters in 38+ predictable states that have just been 'spectators' and ignored after the conventions.
