We’ll all know when it’s time for House Minority Leader Nancy Pelosi, D-Calif., to go.

That’s because she’ll tell us.

Nobody counts votes better than Pelosi — whether it’s ginning up support for ObamaCare or marshaling votes for her own leadership contest.

Some Democrats turned on her when Democrats failed to get within striking distance of reclaiming the House last fall. Those same Pelosi critics returned to the cutlery drawer this week when Democrats wore the collar, going 0 for 4 this year, in a series of special House elections.

We’ll know if and when Pelosi decides to step down from her leadership post or retire from Congress — because she’ll know, too. Pelosi will know if she has the support of House Democrats to continue.
