They include "some" right-leaning projections as indicated by the "R". I'm unsure if there's so few of these due to bias on their part or a deficit of right-leaning sites with projections. Their may be more left-leaning than right-leaning sites on the Internets*, and/or some right-leaning sites may not be posting projections because they're feeling pessimistic and don't won't to memorialize what could be another bad year for the R's.

No, Jim, no projections of my own. I feel that I spend a little too much time obsessing about politics as it is without firing up a spreadsheet and monitoring all of the polls (not an indictment of you doing the same, and look forward to your updates as E-day approaches).

*-It's safe to say that the Internets lean left as the average Internet user is younger and better-educated than that of the non-Internet user, especially among those who would create their own site or blog.
