We are only about 30 days away from the start of the primary/caucus party delegate selection process -- and only about 60 days away from the Super-Tuesday primaries (where 12 states will choose Republican delegates and 10 states will choose Democratic delegates). The delegates chosen on March 1st will not be enough to put anyone (from either party) over the top -- but it could well give Hillary Clinton a huge lead in delegates (since all of the Super-Tuesday states currently show Clinton with a large lead).
I hesitate to even guess how Super-Tuesday will work out for the Republicans. Currently, it looks like the two strongest candidates are Ted Cruz and Donald Trump -- but the GOP race has been very volatile, and that volatility could continue even past Super-Tuesday.
The biggest prize on Super-Tuesday is probably Texas. On March 1st, Texas will choose 155 Republican delegates and 222 Democratic delegates. Another 30 delegates for Democrats will go to elected officials and Executive Committee members (which may or may not be uncommitted). That's a pretty good hunk of delegates for both parties, and they will be apportioned according to the vote percentages.
Here is a bit of background on Texas politics from the Fort Worth Star-Telegram:
