no, there is not . . . enough with the scaremongering
In any coalition there is risk.
The AFC and APNU most likely have different interpretations of this agreement. The AFC likely over estimates the amount of latitude that they will be allowed to operate unilaterally by the PNC, should the coalition wins. The PNC likely under estimates the fact that the AFC will see itself as a co partner and not as a junior partner.
This is especially as even WITHIN the PNC and the AFC there are different factions with their own competing interests.
Your response would look more intelligent if you agreed that there was risk, but that you predict that both Granger and Nagamootoo possess the political maturity to convey to each other, and to the various factions within their own parties that potential conflicts will be managed appropriately.
