Rarely does a party win the white house three terms in a row....simple as that.
Except for 1980-1992, 1932-1952, 1920-1932, 1896-1912, 1868-1884, and 1800-1828, totally. Except for those 104 years of our 224 years of presidential elections, it simply never happens.
Ill bet everyone of those instances when the party won a third term, they won a 2nd term by a large margin, not the third closest in history. I do agree that it is more likely to happen in 2016 than in the past because the GOP has the blame of Iraq and Economic meltdown
You would be incorrect. McKinley vs William Jennings Bryan was close, Hayes won controversially in 1876, and it did not effect the party victory 4 years later.
All of this is nonsense anyway. People don't vote based on the position of the stars. Democrats could lose in 2016, they could win 2016, we could go 48 years without another Republican President, we could go 100 years without another Democratic President. We could go on a string of 20 consecutive one term Presidents each defeated by the next challenger on the opposite party.
Precedent doesn't determine what happens next. Public opinion polls suggest what happens next and they are suggesting Hillary.
Precedent does matter, even if there's no guarantee that patterns will continue.
As for opinion polls, two years ago, there were plenty of times when McCain was leading Obama. Hillary also led Obama in every national poll taken in 2007 (the one exception was a 2007 gallup poll that had a one point lead for Obama but that was if Clinton's husband's Vice President had been in the race, which didn't end up happening.)
Polls and precedent do provide significant information, but it's not a guaranteed indication of the outcome.
Most social issues are moving in a secular direction even if the south and Mnt W still hold sway on the G o P. Voter ID law in WI, was recently ruled unconstitution and union collective bargining.
The precedent of two consecutive terms and switch party control should be thrown out window. Even in 2014, there was no realignment. The states the GoP won in were ruby red. I expect the trend to continue as Dems will win over constitutiencies and win elections even further.
