The dems are riding at an all time high, cocky in their assurance that the have the demographics 'locked up' and that hillary will easily crush any opponent. Here sre some reasons why they probably shouldn't be dancing on the graves of the opposition just yet.
1. Statistically, the opposite party usually has the advantage following 8 yrs of one party rule. Obama ran following 8 yrs of one of the most disastrous and disliked presidents ever.Hillary will be running following 8 yrs of one of the most devisive presidents in recent times. These circumstances worked heavily in obamas favor; they will not be working in Hillarys favor.
2. The enthusiasm gap: in 2008, the dems were super fired up after bush. Obama had massive enthusiasm advantage. Following 8 years of the most liberal president ever, who has been going for broke on the most controvertial agendas possible, the enthusiasm gap is ALREADY MASSIVELY against the liberal dem candidate. After 8 years of rule their base will be somewhat lethargic while the right's base is as fired up as it has ever been. This will be a huge disadvantage hillary faces.
3. Demographics are fickle: no matter what, 95% of the black vote will not turn out for the rich old white lady. Period. Hillary cannot count on the same massive, historic black turnout obama had, for obvious reasons.
Also, 70% of hispanics cannot be counted on to vote hillary. Hispanics do not vote nearly as party line as the liberal media makes it seem. Especially if the repub candidate is hispanic. So the incredibly one sided 'minority' numbers obama got will certainly not be repeated with hillary, at least not to that extent. Also, do not discount the huge numbers of yuppie liberal whites who voted for obama largely because he was the first black contender and it made them feel real special and politically correct to vote for the black guy.
4. Don't write the obituary for a party just yet: recall that following a very unpopular dem jimmy carter in the late 70's was 12 straight years of republican rule, during which time reagan won something like 48-49 states. Unheard of landslides. But the democratic party did not die, no matter how obsolete they seemed at the time. And if the repubs seems in bad shape now, they aren't close to what the dems were in the 80's.
So whereas there were a number of significant factors which all came together perfectly for candidate obama, many of these will NOT be present for candidate hillary (despite what libs currently believe) and in fact there will be a number of significant factors working AGAINST her. If she runs against an actual conservative, she will likely lose.
