Merkel just needs one positive surprise (then she'll win the next election and be done with this ridiculous coalition).
So look for her to propose something radical...something surprising...something that the German people will back by more than 50%.
I don't know that particular "thing," but I'll show a wholly incomplete list of guesses:
1. Re-opens German (or nearby Czech) coal mines for unlimited mining to supply a grand German coal-to-gasoline business program
2. Re-builds the German military under the guise of creating a new NATO natural disaster rapid reaction "humanitarian" force (possibly conscripting all able-bodied unemployed)
3. Declares Germany a no-tax zone in perpetuity for any foreign company willing to move to Germany to set up headquarters there
...or some other bold policy proposal.
Merkel needs just one big idea. After that, she'll run the tables at the next election. Expectations are LOW, so she'll soar above those thoughts and deliver MORE than was expected...making her very, very popular.
