Are Democrats in trouble if Hillary's campaign collapses?

NO!

The Republicans have nobody who can cut into the Blue Firewall which has shown itself willing to vote for just about any Democrat for President.  Such leaves the Republicans with several states that they absolutely must win and cannot guarantee.

The Republicans now basically need a new Ronald Reagan to win, someone capable of exploiting disappointment among Democrats. We are unlikely to have a failed Presidency because the President that we now have is just too cautious.

A composite of Presidential elections, 1976 and 1992-2012:

 
Deep red -- Democrats win every Presidential race. 248
Medium red -- Democrats win all but one Presidential race. 15
White -- always went with the winner 22
Pale blue -- went for the winner in all election, but in that exception went for the Republican 38
Yellow -- twice Democratic, but seeming to now drift Democratic 13
Green -- twice Democratic but seeming to drift Republican (Missouri in a light shade because Obama was close in 2008, others deep green) 38/48
Medium blue -- Republicans win all but one Presidential race. 56
Deep blue --Republicans win every Presidential race. 98

NE-02 is the middle box in Nebraska even if the district is Greater Omaha.

Mass dissatisfaction with the Republican party is strong outside core GOP areas. Republicans will need either a catastrophic failure of the Obama Administration or a quickly-forming cultural trend (like a right-wing religious revival) in most Blue (Atlas Red) states to create an opportunity.

OK, one might trade Nevada for Iowa... but that leaves the Republican nominee with several must-win states (Colorado, Virginia, Ohio, Florida, North Carolina), none of which will be certain.

The winner of the Democratic nomination gets the Obama campaign apparatus intact.
