Swing state refers to any state that could reasonably be won by either the Democratic or Republican presidential candidate
Due to the winner-take-all style of the Electoral College, candidates often campaign only in competitive states, which is why a select group of states frequently receives a majority of the advertisements and partisan media.
The battlegrounds may change in certain election cycles, and may be reflected in overall polling
Faithless electors
Swing State
Colorado, Florida, Iowa, Michigan, Minnesota, Ohio, Nevada, New Hampshire, North Carolina, Pennsylvania, Virginia, and Wisconsin as "perennial" swing states that have regularly seen close contests over the last few presidential campaigns.
A faithless elector is a member of the United States Electoral College who does not vote for the presidential or vice-presidential candidate for whom they had pledged to vote.
That is, they break faith with the candidate they were pledged to and vote for another candidate, or fail to vote, or choose not to vote.
States shaded in blue are considered by most pundits and analysts to be safe for the Democratic Party, states shaded in red are considered to be safe for the Republican Party.
They are Safe states.
The numbers are updated every ten years with results from the National Census. For the decade 2000-2010, there are 538 total electors. A presidential candidate must receive a majority of votes from the Electoral College, or 270 votes, to be declared the winner.
Maine and Nebraska do not use this method, instead giving two electoral votes to the statewide winner and one electoral vote to the winner of each Congressional district.
HOW?
Caution!
Most state laws establish a winner-take-all system, wherein the ticket that wins a plurality of votes wins all of that state's allocated electoral votes, and thus has their slate of electors chosen to vote in the Electoral College.
No pure democracy!
Each state, plus the District of Columbia, gets a set number of electors based somewhat on population. The number of electors is just the number of Senators (always two) plus the number of Representatives in the House.
What?
The United States Electoral College is a mechanism established by Article Two of the United States Constitution in the indirect United States presidential election system to select the President of the United States and Vice President of the United States. Citizens of the United States vote in each state at a general election to choose a slate of "electors" pledged to vote for a party's candidate.
Not Pure
People do not vote for their president directly, but by the electoral college.
