leaving little else by way

[Basitpasha]

Hello,

I was reading an article and then I found some difficult sentences and some words. I want to ask about those.

1) What can be the meaning of this bold sentence?

This political party is negotiating with the government to cooperate in the passage of a constitutional amendment in parliament, leaving little else by way of crisis in the country at the moment.

2) What is the meaning of "At stake"?

At stake is a National-Party near-majority in the Upper House, giving it a virtual veto over non-budgetary legislation until 2015.

"little else by way of crisis" means little else that could be called a crisis; little else that has the nature of a crisis.

If something is "at stake" then there is a risk that it might be lost or damaged if things do not turn out favourably.
