You wanna try to win that argument against Democrats in Congress?
FR is pretty damn active in supporting candidates, publicizing campaign activities, mustering shows of activist support. Once the general election starts, FR will certainly be aggressive enough in supporting the Republican candidate.
Jim Robinson owns this site, sets the rules, moderates (or his “agents” do) the discussions. So it is not just a non-partisan bulleting board.
If you don’t think the Democrats can make an argument out of that, then you underestimate them.
There's anything but a uniformity on who Freepers generally will support. Anyone who has been around for various election cycles (I've seen five here at FR) knows the battles that can rage over ballot issues and candidates alike.
