I may be wrong, but I believe the Senate calendar scheduled debate on immigration for March, and that calendar was set in January. So the marches were timed to coincide with Senate consideration of the issue.
You both commented as though I have been totally off the forum which isn't the case. There is probably few weeks in the past two years I haven't posted some comment if not 15 times. But it isn't like the old days.
The last year and a half however there is so little exchange of ideas and reasonable debate that it keeps those of us that don't have the time on-line that some do to participate in the food-fight thread format we get on big issues now.
However, I imagine for every one of the long time members, like me, that still lurks and reads, there are four that have just ceased visiting on a regular basis.
