Two Guesses

[War on Want]

Ummmmmmmm I hate to be an asshole but lots of your predictions seem to be pretty shaky/partisan to me. Then again mine are too, hope/bias is on all sides, just saying.

[War on Want]

By 2025,
- Will WMDs be used?
Nope, our security systems have evolved to the point where this is pretty possible. Terrorism is mostly on the run and its days are numbered especially if the American government becomes even a little popular in the Middle East
- Will there be another war?
More likely but I would see another war in the future being more of a humanitarian war and less of a war for other reasons. Also chances are it would be small.
- Will there be a reccesion?
Yes, almost for sure.
- Will there be a depression?
Possibly, I doubt it though.
- Will life-saving science be abandonned?
No, I see the world as a whole becoming more scientific.
- Will any other potentially world-changing sciences be abandonned?
No way, except possibly cloning and other "immoral" forms of science that could be applied to agriculture and end many food shortages.
- Will there be a large disaster that is much bigger than Katrina on the United States?
I think most definatley this will happen, though it will be a multi-pronged disaster.

Another thing to consider-

What will society be by 2080-2150?
Oh boy this is hard to predict. I think American society has two paths, one that is much more White, more nationalistic, and that leads to the downfall of American society with possible chaos erupting. It depends on events though but this is very possible.
Another possibility is that we become much more multicultural, liberal, a la European society and essentially become an extention of what I like to call the modern first world society, aka very secularist, very free market based but with cradle to grave benefits, high technology, but the main difference is we would very possibly be competing with them.

I'm not sure "partisan" would apply to my most recent answers.

I do think that if Republicans are elected that are seen as being outside of the "religious right," that will weaken the influence of the religious right.

I'd say the same about Black voters and the Democratic Party. 

No I meant with terrorism. I should have clarified, also I thought your assesment of Obama was a little partisan. I don't think it would be a great presidency but worse than Carter...

[War on Want]

Let's play the hand out

Scenario 1: McCain wins

Let's presume McCain wins and gets in his 2 justices plus a compliant dem congress. We're talking repeal of Roe V. Wade, continued strong FCC, etc. Removing Roe V. Wade removes the conservative base's single rallying point and energizes the left. We're talking a move to the left on social matters not seen since the 60s/progressive era with the trend against neoliberal/washington consensus economics still going on but not being spurred by this. Basically, things change to the point where in 2012 I have a bit of a hard time deciding who to vote for and in 2016 I vote down the line republican because the democrats were too socially left for me.

Scenario 2: Obama Wins

Obama wins and manages to move things slightly more in a moderate direction but his incompetence drives things off the rails leading to a backlash. The end result is a deadlock on social issues on the federal level, de-emphasizing morals/nanny state controls in favor of focusing on security concerns. We're talking 20s red scare level purges against muslims, mormons(the whole xenophobia plus percieved polygamy bit), elements of the far left(the blame america crowd, anarchists), greens, minority ethnic nationalists and some of the more strange lifestyle movements(the transgender movement is crushed to the point where it doesn't recover for a generation, the more outre elements of gay culture are repressed, hippies are repressed, goths/emos get repressed). Identity politics is savagely repressed.

Really?
